Maybe the trick is being pragmatic all the way down and having a TS-like language (with Pythonic syntax) that's compiled to Python.

Mypy started out life as a separate language with pythonic but not Python-compatible syntax and multiple backends that was plannining to take advantage of static typing information and avoiding a GIL to be more performant than Python when compiled to native code rather than using the Python backend. It later developed a Python-compatible syntax, before becoming a static typing front-end for Python. Outside of JS land (and that only because of the browser being an environment where the only universally available thing is JS, though WebAssembly maturing may radically change this), there's not really a lot of demand for a separate language that fixes perceived warts in a target language but otherwise hews very close to the target and compiles to that target. Languages that aim to improve another languages ecosystem usually target the same VM instead of being transpiled, and usually offer different style syntax (e.g., Elixir for Erlang.)
