It should be trivial to poison python, at least for scripts that use #!/usr/bin/env python. Just add a python wrapper in the scripts directory. (We have done this for pkg-config to find recipes that lack inherit pkg-config.) What to do about scripts that use #!/usr/bin/python, I do not know...

I think that is a good idea.. When I looked back in August there were still
support scripts that appeared to be python2.  Also I think other layers
(meta-openembedded) had a bunch of python2 uses in them.

I'm wondering if there needs to be a way to poison 'python' and 'python2'
executables to find these.
