Overview

https://github.com/typescript-eslint/typescript-eslint/pull/7466/files#diff-3cc43b506517aba406ae3a31d7998b116c4b09db76b632c6cb3c2e54fc71d66cR33 shows code that wants the type parts of a type that can be either an intersection or union. Maybe it'd be nice to expose a simplified function to do this? Maybe with a recursive?: boolean parameter/option?

My instinct is no, since folks can do this pretty on their own in a straightforward manner. But just thinking out loud.

I came across a second place in typescript-eslint that would benefit from a basic version of this function. Seems like a good enough reason for me.
