Wouldn't that circumvent any .py(c|o) writing?

I think using an import hook to prevent writing .pyc files is way too much work. You can't use the built-in code because that does write the .pyc files, so you have to redo all the work that the standard hook does.

But it's another fine use case for a to-be-written PEP-302-compliant ihooks.py replacement. I'll make a mental note.
