LGTM, thanks! ✨

Just the one suggestion on adding a notice to the deprecation, what do you think?

[JoshuaKGoldberg]

💯 thanks!

[bradzacher]

we probably want to remove these @deprecated tags.
most plugins will support ESLint v7 and v8 - they're not limited to 8.40.0
this means that trying to direct consumers to use these new APIs is an impossible state as they have to do things like context.cwd ?? context.getCwd() - which is just worse code than context.getCwd().

[so1ve]

You are 100% right - shall I open a new PR?

[JoshuaKGoldberg]

Hmm, that makes sense.

@so1ve if you want to get another PR to typescript-eslint under your belt 😄 we can merge it any time before Monday midday EST. I'll set a reminder to send one in if one hasn't yet been by then.
