You're right, I was mostly just being snarky - but, that said, the source of SRC (sigh - what a terrible name, as others have said) is, in fact, just one Python file, so I suppose you could arguably use SRC for it.
Hah. I just looked at the src (heh) - you're right, one file. I take back my argument.
If esr wants to fetishize a time when Real Programmers took patches over nntp and applied them in rcs, then by god he should go all in and self host the thing!
I don't find it at all compelling either.
