My understanding about the use of advanced/more expressive TR features is that it's OK if you don't use them, and don't bother wasting time for most products. Bot if you are writing a library of framework in TS, go ahead especially since they are meant to improve the experience of consumers.

every feature that makes a language more complicated will eventually hit you. It might make the typescript compiler slower, harder to refactor, your lsp might also get slower, etc...

One person on the team will use them, if you don't put up a linter that prevents usage.
