Whether it is outweighed would also depend on how likely and frequent
the presumed problem is, no?

If Apache creates a folder for me that I cannot remove, most likely,
there was a configuration error in the first place: common practice
tells that you should execute user code under user permissions, not as
www-data. If your code does get run as Apache, this also opens a way of
not asking for help: just put "os.system('chmod +w /.../__pycache__')"
into your code, and have Apache run it again.

So I don't think this is any more unfriendly than creating .pyc files in
the first place, and the advantages of uniformity of this new approach
certainly outweigh the disadvantages.
