I don't see why you need to backport it for that? Apps only depend on a single OCP version, so you either have the baseline entry or you remove it.

I don't see why you need to backport it for that? Apps only depend on a single OCP version, so you either have the baseline entry or you remove it.

Apps that support against multiple versions, install all the different OCP versions on CI, so they check psalm against all those versions, which totally makes sense.
I have it in the baseline now and psalm complains that it would no longer be needed, but when I remove it stable30 fails.
