If we don't throw when accessing on non-leyed property when the descriptor is kedyed, shoud we also remove this, to be consistent?

I was wondering about that as well. The original issue was a backwards compat issue with existing APIs so not throwing there makes sense. Throwing for the new APIs I think is OK and desired to help catch issues (as originally intended).
Other than consistency, can you think of a scenario where we would want to return null for the new APIs?

Nope it's only for consistency's sake. It's fine to me to throw here otherwise

Fixes #95789
This fixes a regression for cases where
ServiceDescriptor.ImplementationInstance\Type\Factoryis called for code that is not servicekey-aware. Instead of throwing,nullis returned.This will be backported to 8.0.
