That needs discussion on llvm-dev to make sure everyone is on the same page, GettingStarted.rst is updated etc. Forcing just a single script to python3 is not a good idea.

FWIW I don't understand why we waste time making our script compatible to python2 and python3 at the same time, it just doubles testing efforts. I'd rather see us go all-in on python3 (or stay with python2 and don't bother). And I personally think we should go all-in for python3...

Well installing any homebrew or macports python (which is often a dependency for other packages) will give you a python2 with the proper symlinks in place. It's usually people maintaining CI infrastructured that are bothered by macOS (or linux) default installations.
