I noticed this evening that
getOwner(this).lookup('thing:foo', { singleton: false })was no longer working as documented here https://api.emberjs.com/ember/3.25/classes/ApplicationInstance/methods/lookup?anchor=lookupAs best as I can tell, this API has been broken for at least 5 years. Given the long length of time this has gone unnoticed, we may simply desire to remove this functionality entirely and not restore it. Users have an alternative using
factoryFor.
