Comment:

 I recommend against moving forward with this approach. We haven't
 introduced new primitive capabilities since WordPress 3.0, and that is for
 a reason. Migrating databases like that should not be required and can
 easily cause issues, specifically with larger multisites. There have been
 numerous capabilities introduced since 3.0, but these have always used
 either the `map_meta_cap` or `user_has_cap` filter, granting them
 dynamically.

 I think we should introduce these capabilities as dynamic capabilities
 using the `user_has_cap` filter, making them what I have so far called
 "fake-primitive" capabilities (only for the lack of a better word). See
 #44468 for more information on that.

 Since this ticket has been moved from 5.1 to "Future Release" before, it
 seems to not be super-critical for 5.1. Let's tackle #44468 and this one
 as an enhancement for 5.2, to have sufficient time for a proper
 implementation. I'll move the two tickets to that milestone now, and I'm
 happy to work on it. For the unit tests, this ticket is blocked by #44468.

 If I was mistaken and this ticket is more critical, I suggest moving both
 of them to 5.1.x.
