The pyuic tool generates boiler-plate code and it needs to maintain backwards compatibility. So there are several aspects of these modules that differ from how you might write the same code yourself.

But really, why should you care about this? Obviously, there is never a good reason to edit these files yourself, and it is easy enough to exclude them from version control. So apart from ensuring that they are re-generated whenever appropriate, you can more or less forget that they are there.
