We build our own applications which run Python interpreters internally, so the auto-discovery won't work. It also doesn't seem to work for venvs either since the venv's `python.exe` is under `Scripts` which makes it not able to find things either on its own.

I've worked around it so far by just ignoring `Activate.ps1` completely and setting up PATH, PYTHONHOME, and PYTHONPATH instead, but this tells me that `Activate.ps1` probably needs some consideration for other use cases. The layout certainly seems wrong for auto-discovery at least.
