The core functionality change looks great to me, thanks!

Same comment as https://github.com/typescript-eslint/typescript-eslint/pull/6641/files#r1141148693 though: I worry about edge cases. Could you add some more testing around those syntax shenanigans please?

[JoshuaKGoldberg]

🚀 excellent, thanks for this one too!
