Still, that's a common need. "I want all Python files in a subtree".

I don't know why "walk" is supposedly more recursive than "glob".

Because the walkdir spelling (IIUC) is longish, tedious and awkward.
I could see myself typing "rglob('*.py')" in a short script or an
interpreter session, without having to look up any kind of docs.
Certainly not the walkdir alternative (I've already forgotten what it
is).
