I'm not seeing an incentive structure for them to change being the only source of good workflows for their users - it's their whole thing "It just works" - regardless of if it's true in practice or not.
If you want the "it just works" experience, you can still buy the Apple products though, that's not changing. You just also have the option to not do so.
If Apple knew they would need to expand this feature past their gear, possible they’d never have implemented.
We may never know what stays unimplemented due to this.
(This is a neutral take - note I do not have a personal opinion formed in this “debate”.)
