Exactly this. I recently created a tiny DSL (can be trivially parsed with .split('\n') and regex) for a side project. I wanted to create a very simplistic syntax highlighter for it in VSCode, but I realized I needed to create an extension using a code generator, and write a bunch of manifest files. In addition, to use/distribute the extension without having to run VSC in development mode means I had to create a developer account, generate some token, and publish it to the marketplace.
