Can you create a new function and call it from integrations.Manager.ApplyConfig instead? Filtering the actual slice here will omit the config from the results of /-/config which might be a little confusing to users.

This got more complicated. When you remove a configuration it did not stop the scraper, so when a configuration is disabled/removed and reload called Agent would list scrape_error = 404. Since the integration had stopped but the scraper was still running.
