Currently, you can put a file on disk and import it immediately; that will stop working.

One thing I should add is that if you try to import a module that wasn't there before, the interpreter will notice this and has the opportunity to update its idea of what's on the disk.

Likewise, if you delete a module, the interpreter will notice when it tries to open a file that no longer exists.

The only change would be if you added a module that shadowed something formerly visible further along sys.path -- in between starting the program and attempting to import it for the first time.

So I don't think there would be any visible change as far as most people could tell.
