[Bf-committers] Moving to Python-3.8

I wouldn't advise on overlooking the VFX Platform.
The "joke" does not come from there but from Autodesk and The Foundry.
The VFX Platform is actually trying to cope with it in a realist way and slowly push everyone to the tip of progress.
Writing pipeline tools compatible between 3.* is not an issue, it's about having extensions working in all the toolset without recompiling and deploying them for each DCC.
If we diverge from the VFX Platform, we will lose this advantage and some industry adoption.
I don’t mean we can't, but it should be for a good reason (or optional)
But more importantly:
One of the major improvement in 2.8 was that we could import python extensions from PyPI.
Let me stress out how this is a *major vital feature* for any small/middle sized animation/VFX studio.
If we choose to overlook the VFX Platform and jump to 3.8, we must be sure to keep Blender's python interpretor compatible with the official extensions (PyPI).
IMHO of course 😊

Native code Python modules, I mean typically C written libs or APIs like Blender's, used to not be compatible between Python releases.
However, there seems to be a part of the ABI that remains compatible between releases, since 3.2:
I don't know whether and how exactly people may mix native modules in and out of Blender in Python VFX pipelines.
But just a note that it may be less a problem now than earlier. Or not, I didn't check how useful the compatible part of the binary interface is.
2 cently, Toni
