Great, so we have some more evidence that support for project-specific env vars is a relevant feature. > The GNU ELPA package wisi takes an intermediate approach; it maintains a > list of project-specific environment variables in the project object, > and let-binds them in process-environment whenever it runs a process for > the project. 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.
