Is your implementation (adapted to a standalone type) something you could put up on the cheeseshop?

Short answer: no.

My implementation (attached to the issue #14162) reuses most of private PyDict functins which are not exported and these functions have to be modified to accept a frozendict as input.

One of the advantage of reusing PyDict functions is also to have a frozendict type compatible with the PyDict (public) API: PyDict_GetItem(), PyDict_SetItem(), etc. This property allows to do further changes like accepting a frozendict for builtins or use freezing a type dict (use frozendict for type.dict).

If you only want to a frozendict type, you can copy/paste PyDict code or implement it complelty differently. Or you can write a read-only proxy.
