Eleventy Dev Server - CLI and watch option

This is a clarification rather than an issue I guess

Testing Eleventy 2.0.0@beta and Eleventy Dev Server 1.0.0, particularly the watch option in conjunction with external NPM scripts for CSS and JS processing. Can I use the --watch flag with the CLI or is the --dir flag the intended method for now ?

Everything works smoothly by doing npx @11ty/eleventy --serve with a JS configuration and setServerOptions

eleventyConfig.setServerOptions({
  watch: ["./dist/assets/css/**/*.css", "./dist/assets/js/**/*.js"],
  port: 3000,
});

Things are working as well with the CLI using a global --dir=\"./dist/\" flag

In some contexts, it would be great to be able to use the --watch flag with an array of globs (to watch files that are not necessarily in a single folder). Is that possible now / could be implemented down the line ? Looked at the Eleventy Dev Server man page but didn't see a way to do it.

Start by comparing the CLI handling of --watch and --dir with the setServerOptions({ watch }) configuration described in the issue, then check the Eleventy Dev Server man page. Done means the supported behavior for watching an array of external globs is documented or implemented, with the CLI and configuration paths agreeing.
