This has already been done in WPGraphQL for ACF

(Just keep in mind that plugin update checking currently happens only if the plugin is active, unlike with WPGraphQL for ACF which is hosted on .org.

So if an "old version" of this plugin is causing a fatal conflict with WPGraphQL, they'll need to manually delete + install the new version.)
