What was the condition that required this previously? It was pre linear IR so I won't be surprised if it isn't needed anymore but I do remember it was quite non-obvious so I want to make sure it's not needed anymore...

I thought it should be OK now because of linear IR, but I could be wrong. CI seems OK with it.

After some off line discussion, we agreed that there are probably some easy case where this is needed previously. Right now, this change should be valid if we assume all objects (special types or not, big or small) are promoted under the same rule. I’m 90% sure that is the case now so it should be fine....... |
