Some of these immediately resonate. I'd love (4) to be a reality but it's going to be a struggle to get there, not that it isn't worth striving for. And while I agree with (5), the "covers" are often complex/dynamic and where a lot of difficulty in implementation and maintenance occurs (Sorta touched on in (3)). (6) is what got us thinking about this idea of distilling entitlements in the first place.
Will definitely reach out. Thanks!
