what is met in the "real world".
But if this update can be done by a simple search/replace on the C source of projects,
I can only perceive two scenarios this will affect: well maintained projects,
for which it is fixable in minutes, and stale packages, no longer released
that "happen to work" when someone downloads and builds for new
Python versions. In these cases, the build will fail. If the person trying
the build can't fix it, but can take the error to a proper, or high visibility,
forum, someone will be able to come to the fix, leading to renewed
visibility for the otherwise stale package.
