I'm looking into using ast-grep fo linting ReScript. What rules should I investigate?

The sgconfig.yml handles platform-specific parsers straightforwardly:

customLanguages:
    rescript:
        libraryPath: # paths to dynamic library
            aarch64-apple-darwin: ./parsers/mac.so
            x86_64-unknown-linux-gnu: ./parsers/linux.so

I have working Linux and Mac parser files locally, so I think we now have everything we need. It would now be a question of designing the DX/UX of the linter. How should it fit into the development workflow, and most importantly, how should rules work? Getting into some highly complex extensibility territory like eslint seems unattractive…

@zth do you have thoughts on any of this?
