Maybe we could refuse creation of case different branch
names on case insensitive file systems, but you could have
created them on a case sensitive file system, so you still
have to work with that.

This topic was discussed at the Git Merge this year (again),
and IIRC the outcome was to not restrict outselves to the
lowest common denominator, but rather ¯\_(ツ)_/¯.
People who use case insensitive file systems are aware of
their limitations and would not ever want to do such branch
tricks, right? ;)

I rather think nobody stepped up to present a
solution that doesn't suck. As by the title of this thread,
it's rather minor.

The hook to tell the user if that branch name is allowed?

My gut reaction to that is, that such a hook would violate
the principles of the DVCS thinking. A user ought
to do anything they want locally including having naming
rights for their local branches, so we'd not want to restrict
them?
