There’s a mode to pretend those features don’t exist and not allow them. Meaning it gets far simpler to just type elide rather than any actual compilation effort. I think this idea is getting more popular and it would be kinda nice if TS committed to not adding any more features like that.

TS has committed to not adding any more features like that. Features only get added when they reach a certain threshold on the TC39 standardisation track.
