I understand the rationale, however, people tend to copy what they already
find. If there are more docs without this section, then it becomes less
likely that someone will include it in future documentation, and it
eventually goes away because this cycle repeats.

I also believe this section helps to balance out whoever is writing the
documentation. Many rules say "this prevents bad things from happening" but
asking people to write a reason why not to use the rule at least makes
people stop and think about the counter-argument. One of the things I hated
about JSHint/JSLint was the presumption that the rules made sense in most
cases without giving situations where it made no sense.

So for this one, it might be a simple description, "This rule is a
formatting preference and not following it won't negatively affect the
quality of your code. If you alphabetizing variables isn't a part of your
coding standards, then you can leave this rule off." Others I expected to
have more verbiage.

In any case, I want to get a strict format in place in order to get the
documentation consistent and reinforce expectations for future rules.
