This is interesting. The things you list as problems are the same set of things we tried to solve:

- automatic compilation that is fast

- sourcemaps work

- decoupling of packages to help compatibility

- automatic tsconfig management

I wonder if you would have a different conclusion with these things taken care of.

I agree that TypeScript makes it easier to have functions with complex parameters - because they are now documented and more understandable. So yes, this demands more discipline on the API designer to keep APIs simple.
