It is solving the problem that python is long past its life:
https://www.python.org/doc/sunset-python-2/

The 5.11-rc kernel diffconfig doesn't work now due
to the /usr/bin/python change to /usr/bin/env python.

Could we please ensure this makes it into 5.11 and/or
maintains the FIxes tag if it does not?

Yes, Python is finally being removed from some distributions
and has already been done so from my yocto builds where
I detected the problem.
