Like Eli said, this seems unwise. But it hints at a logical problem: if
start-process and friends are simply documented to use exec-path and
process-environment, but use their modified values in some
circumstances, someone trying to debug this could have a big problem.
Especially if the feature is implemented not using nadvice, but with
file handlers.
So I think we should either fall back to the idea of using buffer-local
values and make it work somehow, or have environment.el provide its own
versions of call-process, etc, that use the modified environments.
The latter option will require modifying all appropriate callers, but
seems like the cleanest approach to me.
Alternatively, the docstrings of all process-interacting functions
should be updated to mention environments.el, and at that point it would
make sense to just integrate it into the core. Maybe the result would
look similar to what you said, with all process primitives using the new
functions (called e.g. environment-exec-path and
environment-process-environment).
