Great, so we have some more evidence that support for project-specific
env vars is a relevant feature.

If I understand correctly, this works only when launching the WisiToken
program, am I correct?

python.el also supports Python "virtual environments", but this only
applies when running the Python shell.  In my opinion this approach is
too limited, because one also needs the correct environment to start
other types of processes: compile, flymake, language servers, random
private user commands, etc.
