The trouble I foresee us encountering with any scheme which attempts a conversion which retains both Python 2.7 and Python 3 compatibility is code like this:

Is python2 support required for a well-motivated transitional purpose?

I had previously proposed making all our scripts work with both python2 and python3 only because I thought Apple was going to require python2 indefinitely. Now that you're interested in this transition, there's probably no need to continue python2 support. Anyone building WebKit on older versions of macOS can reasonably be expected to manually install python3, right? And it's clear that you're prepared to do this for infrastructure/bots already.

Then million-dollar question is: what shebangs will we use for our scripts? Will #!/usr/bin/env python3 work for Apple?
