[Bf-committers] VFX reference platform 2022 draft

imho 3.9 is the only version they could have picked, the
proposed release date for 3.10 is 2021-10-04 [1]. While
the VFX platform aims to finalize in august [2]. I was
rather vocal last year for them putting versions on that
had not been released yet (some of which got delayed well
into 2021) I'm happy to see for 2022 a more conservative
stance has been taken.

With bugfix support for 3.9 ending on 2022-05-02 [3] that
does put them in an odd situation, they'll either have
to recommend a version that may not be released on time,
or recommend a version that will not see bug fixes for most
of the year. There seemingly is no winning solution here
since the problem appears to be the somewhat short
support window for python releases.

As much as I picked on them last year for making very
strange recommendations, I feel they struck a good balance
for 2022.
