This isn't a proper deprecation as set_active_env would have it's changes persist beyond the scope of f. I think we should probably just make this a breaking change

fair, though this is what the previous change did, modulo also renaming set_active_env.
That function isn't actually exported.
Since the normal way to do it is to use apply(pe) do.
More an internal implementation detail of apply ?

I think I'm okay with stating that set_active_env and get_active_env are internal functions and don't require deprecations. Making this a breaking change would be the safest but I could be convinced to have this be non-breaking.

If it breaks something can always revert, tag patch, and rerelease as breaking

I will just delete them both and not deprecate
