BTW, what's the performance problem in importing unnecessary stuff (assuming pyc files are already generated) ?

larger modules can easily take 0.1-0.2 seconds to import (at least if they use enough external dependencies). that may not be a lot of time in itself, but it can result in several seconds extra startup time for a larger program.

importing unneeded modules also add to the process size, of course. you don't need to import too many modules to gobble up a couple of megabytes...
