MIM account deprovisioning déjà vu

I was doing some research for one of my customers that was having an AD account provisioning problem with MIM. I wanted to make sure that I wasn't introducing a potential deprovisioning problem with my change for them, so I was revisiting the deprovisioning scenarios in my lab.  I hit on this support forum article: FIM 2010 R2 Deprovisioning with Outbound System Scoping Filters (microsoft.com). Reading through that and get to the bottom and see that it was asked and summarized by me. About a decade ago. Totally forgot about that work. No deprovisioning improvements ever came to FIM/MIM. At least AADConnect does a nice job of declarative deprovisioning when falling out of scope of a provisioning rule.
