[Bf-committers] Proposal for clarified VFX Reference Platform Support

That's a good question you're bringing.
For the Python my thoughts are aligned with Campbell.
For other libraries I wouldn't make it an official support in the terms
that it is us who verifies Blender compiles and works with library versions
we don't use ourselves, but we should be open to fixes (assuming they are
small, non-intrusive) from people who actually compile Blender with those
library versions. Very similar to how we support platforms other than
x86_64 and arm64.
