Python is doomed? That's new.

You use python docker images pinned to a stable version (3.11 etc), and between bigger versions, you test and handle any breaking changes.

I feel like this approach applies to pretty much every language?

Who on earth raw dogs on "language:latest" and just hopes for the best?

Granted I wouldn't be running Facebook's backend on something like this. But i feel that isn't a problem 95% of people need to deal with.
