The proposal states that this should work, but this was never
implemented:

We decided to leave this on main and not cherry-pick because of the risk of request cycles being introduced by type resolution. |

6.2 cherry-pick of #81949.
Description: The proposal states that this should work, but this was never implemented:
Risk: This might introduce a request cycle via type resolution, perhaps. Otherwise it should be pretty safe.
Radar: Fixes rdar://91842338.
Issue: Can't inherit from a protocol with primary associated types using the "generic" notation #62906.
