That would be a change in behavior, of course.

Currently, you can put a file on disk and import it
immediately; that will stop working. I'm pretty sure
that there are a number of applications that rely
on this specific detail of the current implementation
(and not only IDEs).

It still might be worthwhile to make such a change,
but I'd like to see practical advantages demonstrated
