While the use case is reasonable (if specialized),

It's not that specialized. You might want atomic updates for coordinating
with C APIs that expect callers to have this capability.

not sure ctypes is the place to expose such functionality, which can be
quite extensive (see https://gcc.gnu.org/onlinedocs/gcc/_005f_
005fatomic-Builtins.html).

You don't need to provide all of those builtins. Users can build them in
Python out of atomic-compare-and-exchange. Only compare and exchange needs
C support. It's not very much code.

Perhaps

as a separate package on PyPI?

I have little interest in a separate PyPI module. I don't want to have to
distribute custom-compiled extension modules.
