I agree that the Antlr Typescript grammar is underwhelming, and I also agree with the difficulty of not having a well defined owner of the project to interact with. My main use case is parsing TS type definitions, and the grammar from the grammars-v4 repo doesn't parse anything starting with 'declare', which is pretty fundamental.
