That's the problem: it does not add much, but it adds some things and
the problem (for me) is to know if these are used or not:
1) It exports PYTHONHASHSEED=1 (needed?);
2) Undocumented features allow to use something else instead of
BaseTools/BuildEnv...
I also think that it would be far better to state clearly what is
needed (including with BaseTools/BuildEnv and the
like) and let builders simply set the correct environment with
defined variables being used afterwards (MAKE, SHELL, PYTHON and
so on).
To state, for example the Python major version required and that
everything depends on GNU make and bash(1) (hence the
/path/to/gnu/make SHELL=/path/to/bash invocation) and that
would be it.
But: who uses it (edk2setup.sh) and with what? This question, I can not
answer, obviously...

Hum... There is a very lethal weapon actually in use: the pillow. I
already sent various patches and they are silently ignored...
If my contribution will be ignored as others have been till now, honesty
should be to clearly state: "we don't care and we won't care" so that
I can use my time trying to solve the problems I want to address at a
different level than UEFI...
