Sounds like a good idea. Threads themselves have that feature,
although I seldom actually use it. But it's great to have available.

You can already do this, although without the keyword arg. You can
simply attach attributes to these objects. It's a quick-and-dirty way
to achieve your goal, but it doesn't require you to wait till you can
move to a new Python version :)
+1, this seems like a useful feature in some situations and not
problematic where it's not needed.
