Is this really needed?

I think you pretty much nailed it by `share.install resource('my_extra_docs'), resource('some_man1')`. It reads so beautifully.
the `Pathname#install` knows how to install files and resources and `install` works with both.

But opposed to that `Pathname#stage` looks disturbing as it can only handle resources and does the same (does it?) as `Pathname#install`
