Description
from: https://github.com/Microsoft/TypeScript/issues/30569#issuecomment-476007534
so basically we need a way to say it clear and loud in the language whether we want:
Promise<A> | Promise<B>
or
Promise<A | B>
as a result of a type operation

Define the proposed syntax and semantics before implementation; done requires an agreed language design and corresponding type-checker coverage.
