For me, not really. If I want to use type annotation, I need to write the types somewhere in order to communicate it to future readers. I would much rather do it via Typescripts annotations than JSDocs. It's not clutter as it was deemed necessary by the writer (me). If I don't want to use type annotations, I simply don't add them and Typescript does not force you to do so unless you tell it to.
