I need to install it if I'm doing LLVM development because it's needed for the tests, but needing it just to build seems like massive overkill.

It is possible that you are right about the overall index of "presence". 
Just to mention that in Fedora derivatives (RedHat, CentOS, maybe 35-50% 
of Linux dev stations - I don't know) Python is guaranteed because of 
yum (the package manager).

Absolutely - once the generators are prototyped and tested in Python, if 
current Perl (presence) > Python's, they can be easily ported to Perl.

Kind Regards,
