i know people been saying kanye has had ghost producers for years. idk how true that is or not, but his contributions to music are far greater even before he started having "ghost producers/engineers". hell without kanye opening up a lane then drake would still be trying to make it as a canadian actor.
Kanye has used ghostwriters since the beginning (rhymefest was the first I knew of that he used) but I give producers a pass with that especially if they're as skilled as kanye.
But yeah I agree with pretty much everything you said
