That's not correct. Look closely at my example: the file ownership
recursively changed from steve.steve to steve.users.

And yet Python provides a chown function despite this alleged
uselessness. Maybe it's not quite so useless as you think?
Here's a thought... maybe sometimes people actually do run Python
scripts as root?
And as the comments to this Stackoverflow post explain:
the ability for unprivileged users to change ownership to another user
is configurable under POSIX.

Fortunately that is not correct, but even if it were, that's no reason
to not allow chown to apply recursively.
