It is unrelated to Phoenix.LiveReload - but it it is an integral part to the live reloading development cycle.
Phoenix.LiveReload won’t have anything to do (frontend asset -wise) unless files in those directories are changed - (watching and) updating the static asset files is the responsibility of the script that is started by watchers - so the watchers configuration is an integral part of the live reloading development cycle even if that is part of the Phoenix.Endpoint rather than the Phoenix.LiveReload configuration.
