I think Torsten's use case was for someone who is carefully curating
their loose and packed-refs, e.g. gc.packrefs = false. This could be
for backwards compatibility (existing ambiguous refs whose names
cannot be changed for some reason) or simply because they want to.

Since refs.ignorecase falls back to core.ignorecase, you could just
set core.ignorecase = true and feel safe when sharing with Windows/Mac
OS. I think having the distinction just makes Git more flexible, OTOH
I can see how having both refs.ignorecase and core.ignorecase could be
confusing and possibly redundant.
