Whatever bad experience you get from the (admittedly) immature tooling, pales in comparison to the intense discomfort or working with an untyped Python code base of even moderate size, specially ones written by many different contributors.

I’ve worked for a while rewriting a large crappy old etl codebase and types were not the problem at all.

Really it needed a huge amount of reorg and refactoring, which a test suite and pyflakes handled quite well.
