Many folks have often (correctly!) pointed out that each language's existing parsing packages will be more guaranteed to keep up with language changes. Our hope is that if we can get a critical mass of useful tools that all use tree-sitter under the covers, there will _also_ be incentives to ensure that the tree-sitter parser for each language stays up-to-date. And because of how tree-sitter grammars typically live in dedicated repos, that work might be done by external volunteers, and not by the core language developers.
Another benefit to our approach is that it should be much easier to adapt OP's linter to work with other languages, since in a sense it's “parameterized” by the language grammar and queries. If you use Python's `ast` module, you can't easily adapt that code to work on Go programs, for instance.
