There aren't many heavy-generics projects in the integration test suite so that's why we might not see any failures here. But I feel like this should be behind bleedingEdge config because it detects NEW situations in the code. |

As a follow-up on #2311, I think the
$isStaticcondition was originally meant as an exception for constructors, and was widened to static methods by mistake, because it produces false negatives (https://phpstan.org/r/1bb14b3f-5dc5-4417-9e27-8c0e4c886987).Now that variance in constructors is ignored entirely, we can just remove the conditional and treat parameters in static methods as contravariant.
I’m not sure about the BC impact of this change though. It’s technically a bug fix, but it might disrupt some existing builds. I’m curious to see if any integration tests fail.
