I think that using "outside set" and checking if file is in this set is kind of performance issue, as finishModules hook is called only once we can came with better solution:

const resources = Array.from(modules)
          // @ts-ignore
          .filter((module) => module.resource)
          // @ts-ignore
          .map(({ resource }) => resource.split('?')[0])
          .filter((resource) => resource /* && !seen.has(resource) */ && isMatch(resource, wanted) && !isMatch(resource, exclude));
const resourcesUnique = new Set(resources);
//...

By moving the finishModule hook we no longer spread the linting work out... one lump (in my case 5620 files) gets sent to the linter in one go. The thread pool (if threaded) does not fill up... only one worker gets all the jobs.
