Looks to me like it's just doing the normal tab-completion of globals,
rather than having a special case for the 'import' statement. So what
you're talking about here is a feature request:

When the input begins "import ", please can tab-completion enumerate
available modules?

This is a very plausible feature request, but be aware that it will
involve a very costly disk search. Figuring out what modules could be
imported means going through the entire Python module search path,
enumerating .py (and other) files, and that could be a lot slower than
you think.

It might even already be available, but disabled by default (because
of that cost). But someone other than me will be better placed to
answer that.
