Two months and 30 days, don't exaggerate, man! :)

FWIW, the "shebangs" in that directory are no-ops. Those are extensions
read into sphinx, not standalone programs; they go into a Python 2 sphinx
instance just fine.

Which isn't an argument against dropping Python 2, of course. That's
really just a matter of when.

Delightful - and wrong; moving that line around doesn't change anything.
The crash comes from deep within sphinx; the more I look at it the more
confused I get. Stay tuned...
