Hi Matti,
I think this makes sense and will fix a common issue people upgrading
to PyPy 3.12 will run into if we do nothing.
Can you clarify a little what the status of PyPy 3.13 is? Will PyPy
try to keep up with CPython once again or is 3.12 going to be the last
major version upgrade for the foreseeable future?
Clarifying that will help us figure out what to do when we drop Python
3.12 support.

We will begin work on PyPy 3.13 soon, and expect it to be ready before
May 2027. The hardest features to support going forward (looking at 3.14
as well) are free-threading and subinterpreters. Currently we think we
can support the C-API side of free threading but the subinterpreter
support will require a major refactoring of PyPy startup internals, and
the return on investment is not clear.
