FYI, rebased onto master bco. #20828

@berkerpeksag What about ditching the whole Cache/Node stuff and just use functools.lru_cache? Pro: It would get rid of a lot of code. Con: It might be a little bit slower. Worth pursuing as a future enhancement?

I'm usually not a fan of changing code that has been working fine for more than a decade, but let me think about it a bit.

I'm going to review this PR this week.

Great, thanks.
