Is it not cheap to replace the python2 dependency by the python3 one
and try to locally build?

The snippet of code you sent helps to figure out which packages are
still using Python2.

As you said, some packages will not be updated to Python 3. Let
document it in description for example and let provide a rationale
explaining why that we put in the manual.

It does not appear to me a reasonable approach.

Agree! :-)
