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?
