That's fair; OTOH, these are the project's dependencies, which is
nothing to do with whether you're using a venv or not. Doesn't make a
lot of difference (unlike NPM's package.json, which absolutely has to
be called that, or tools won't find it), so do whatever makes sense
for you.

Ossifying doesn't mean "turning into Open Source Software", but I know
I've had messy directories sitting around as I OSS-ify something :)
