If you look at the C code, you find that there are very few callers
to GivenExceptionMatches (even if you also count ExceptionMatches
callers), and they either pass a PyExc_ object (which will automatically
be permitted), or one of their own exceptions. If you were to remove
PyErr_GivenExceptionMatches, and replace it with something else
where
a) people have to change the functions in their code, and
b) have to check the return value for errors (which they can
statically determine to never happen)
I think the authors would be unhappy about this gratuitous change.

Please don't.
