Yeah, this is why I wince every time TS gets another feature.

IMO it was entirely good enough for what it does quite a while ago. No need to add more—that's purely introducing risk (of the language's ecosystem getting worse, mainly) from my perspective.

On the contrary, many of the new TS features over the last year or more have been around making type inference smarter and allowing for less explicit typing

Yep! Or making type checking safer (this list is enormous), or better aligning TS specifics with how JS is actually used (upcoming 5.0 getting import specifiers more or less right as a great example).
