Black, itself, changed rules many times within a 1-year period to the point our own CI would fail on existing code that previously passed.

You problem isn’t that black changed formatting rules, your problem is that you didn’t pin CI dependencies. This isn’t a unique problem to black, any other tool used in CI pipelines can cause things to break if you don’t pin them.

Indeed. Something wihout security impact will use pointless resources when you update. Do it rarely (or never if possible).

It's funny you say that, because Go and Python are two of my least favorite languages, partially for reasons of formatting.
