This also works with the Python interpreter in the shebang line.
So if your "make install" for "mytool" creates a venv in
/usr/local/lib/mytool/venv and then replaces the shebang in
/usr/local/bin/mytool with "#!/usr/local/lib/mytool/venv/python", the
user can just invoke "mytool" without caring about the virtual
environment.
If you do that for every Python script, size may be a problem, though: I
just checked a few of my venvs, and they are between 13 and 418 MB:
Average 81 MB.
