I didn't check, but those are the current minimal versions above 3.5 for

[1] Checked with:
vermin -v $(git ls-files *.py)
Please notice that vermin is not perfect: my script passed as version 3.6
because the f-string check there didn't verify f-string improvements over
time. Still, it is a quick way to check that our current minimal version
is not aligned with reality.
Btw, vermin explains what is requiring more at the scripts. For instance:
$ vermin -vv scripts/checktransupdate.py
...
!2, 3.9 /new_devel/v4l/docs/scripts/checktransupdate.py
