The question isn't so much whether it's useful, as whether it's of
sufficiently general use to warrant putting it into the core language
(not even the stdlib, but the C core!). The fact that you have an
implementation of your own, actually indicates that not having it in
the core didn't cause you any real problems.

Remember - the bar for core acceptance is higher than just "it is
useful". I'm not even sure I see a strong enough case for frozendict
being in the standard library yet, let alone in the core.
