ContextVars are seemingly more robust and work with async. We use them quite extensively for adding context to logs.

I was going to say the same, I combine ContextVars with LoggerAdapters[1].

TIL that ContextVars can work in place of thread locals too. Thanks for pointing that out!

I had mistakenly assumed ContextVars only worked for async code.
