Indeed. There's also embedding, where I suspect there's a much higher
likelihood that performance isn't key.

And in your survey, I'd split out "needs the Python/C interface to be
fast" from "needs internal operations to be fast, but data transfer
between C and Python isn't as critical". I suspect there's a lot of
people who believe they are in the former category, but are actually
in the latter...
