I agree.

I'm strongly against StrHash itself because of the reasons which matz mentioned.
String is not Symbol, Symbol is not String. It is useful in a
particular case but Ruby is a general purpose language.
When you need different-access, you can implement "your language" on
top of Ruby like HashWithDifferentAccess. This is a good point of
Ruby.

compare_as_string_key is much more acceptable. But it still seems to
be just for Rails.
How about Hash::Type class as an API for rb_hash_type?
It means, generalizing compare_by_identity and HashWithDifferentAccess
to strategy object that represents how to compare the keys.
