it's not unusual for some "move fast and break things" OS vendors to change
APIs in incompatible ways, update toolchains in incompatible ways, e.g. Apple
does it quite often, as we learned over the years. And do not forget rolling
release OSes.
python (minor) releases come up every 2 months, sometimes every month. I gather
it's in response to the OS updates, in part.
Our releases are less frequent, and we often don't check that Sage works on
such and such betas and pre-releases.

no, not really. On some Linux OSes like Debian, some open-source BSDs perhaps,
on others much less so.
E.g. Apple's XCode update released a short while ago has broken Sage 10.6. (as
the C++ compiler got a version bump).
Vendors of maths soft should not want to come close to components which closely
interact with the OS, such as compilers and interpreters, unless they just
cannot avoid it. In case of Python it's surely beneficial not to come close to
it, as Python's vendor does a very good job in doing ptompt updates, a surely a
much better job than our attempts to vendor them.
Same applies to compilers.

Tell this to Apple, RedHat (i.e. IBM). :-)
