Sounds like a good compromise. I agree about the default, except that

I have now implemented this (apologies for the delay). I attach revised patches.

As of commit 2809012 we have a new primitive, file-name-case-insensitive-p, that can be used to determine whether or not a filesystem is case insensitive. This is better than relying on system type. For example, on both Cygwin and macOS, it's possible that some filesystems are case-insensitive and others aren't.

Thanks for the heads up, that's great news! It bothered me that there was no easy way to do this previously.

I updated my patch so that dired-omit-case-fold is now a three-valued variable which defaults to 'filesystem, and a helper function that checks (filename-case-sensitive-p dired-directory) when this value is used.

I've added info and NEWS documentation for dired-omit-case-fold.
