> Maybe in the pursuit of an opinionated language, even if the designers are reasonable at the language's inception, the community throws out logic and "opinionated" becomes a in-group out-group tribal caveman situation.

I think you've got this backward. It's not that the particular choices are important. It's a thing happening on a higher meta level than that.

Some programming languages are, by design intent, "living" languages, evolving over time, with features coming and going as the audience for the language changes.

"Living" languages are like cities: the population changes over time; and with that change, their needs can shift; and they expect the language to respond with shifts of its own. (For example: modern COBOL is an object-oriented language. It shifted to meet shifting needs of a new generation of programmers!)

If you were able to plot the different releases of a living language in an N-dimensional "language-design configuration space", these releases would appear to arbitrarily jump around the space.

Other languages, though, are, by their design intent, "crystallized" languages — with each component or feature of the language seeing ever-finer refinement into a state of (what the language maintainers consider) perfection; where any component that has been "perfected" sees no further work done, save for bugfixes. For such languages, creating a language in this way was always the designers' and maintainers' goal — even before they necessarily knew what they were creating.

"Crystallized" languages are like paintings: there was an initial top-down rough vision for the language (a sketch); and at some early point, most parts of the design were open for some degree of change, when paint was first being applied to canvas. But as the details were filled in in particular areas, those areas became set, even varnished over.

If you plot the successive releases of a crystallized language in design configuration space, the releases would appear to converge upon a specific point in the space.

The goal with a crystallized language is to explore the design space to discover some interesting point, and then to tune into that interesting point exactly — to "perfect" the language as an expression of that interesting concept. Every version of the language since the first one has been an attempt to find, and then hit, that point in design space. And once that point in design space is reached, the language is "done": the maintainers can go home, their jobs complete. Once a painting says what it "should" say, you can stop painting it!

If a crystallized language is small, it can achieve this state of being entirely "finished", its spec set in stone, no further "core maintainer" work needed. Some small crystallized languages are even finished the moment they start. Lua is a good example. (As are most esolangs — although they're kind of a separate thing, being created purely for the sake of "art", rather than sitting at the intersection of "work of art" and "useful tool" as crystallized languages do.)

But large crystallized languages do exist. They seek the same fate as small crystallized languages — to be "finished" and set in stone, the maintainers' job complete. They just rarely get there, because of how large a project it is to refine a language design.

You might intuitively associate a "living" language with democratic control, and a "crystallized" language with a Benevolent Dictator For Life (BDFL) figure with an artistic vision for the language. But this is not necessarily true. Python was a "living" language even when it had a BDFL. And Golang is a "crystallized" language despite its post-1.0 evolution being (essentially) directed by committee.

The friction you're describing, comes from developers who are used to living languages, trying to apply the same thinking about "a language changing to serve the needs of its users" to a crystallized language.

Crystallized languages do not exist primarily to serve their users. They exist to be expressions of specific points in design space, quintessences of specific concepts. Those points in design space likely are useful (esolangs excluded); but the expectation is that people who don't find that point in design space useful, should choose a different language (i.e. a different point in design space) that's more suited to their needs, rather than attempting to shift the language's position in design space.

Adding a bridge is a sensible proposal for a city. You can get entire streets of buildings torn down to make way for the bridge, if the need is there. But adding a bridge is not not a sensible proposal for a (mostly-finished) painting. If you want "this painting but with a bridge in it", that's a different painting, and you should seek out that painting. Or paint it yourself. Or paint the bridge on some kind of transparent overlay layer, and hang that overlay in front of the painting.

Conveniently for this discussion, Borgo here is exactly an example of a language that's "someone else's painting, but now with the bridge I wanted painted on an overlay in front of it." :)
