My argument for requiring a PEP is that this change will not only affect
the people maintaining the clinic code. It will affect everyone
contributing and maintaining code in the CPython codebase. It's much
more than "just an addition to the C API", it's a change in how CPython
is developed.

Writing and proposing a PEP brings public scrutiny in a much more
visible, and also better-recorded, way than a bug entry on a tracker.

Note that writing a PEP doesn't mean that there'll be a huge discussion
about it. And you needn't post it on python-ideas, you can post it on
python-dev instead.
