The Python API just mirrors the Qt one, and every QObject has "parent"
as last argument.

Yeah, that'd be something for this mailinglist instead:

However, that'd collide with how keyword arguments are used already:

PyQt doesn't have any dedicated documentation really. PyQt wraps over
1000 classes. Translating all Qt documentation to Python (and, more
importantly, keeping it synchronized with all Qt doc changes) would be a
massive effort, with a relatively small benefit.
