> This sounds like a backend pass for out-of-tree usage, so we might have to keep the legacy version

In our custom pipeline downstream, we enable this pass late in our `opt pipeline` So, this change wouldn't affect us. However, in the LangRef, we state it can be lowered pretty late  - which means someone (any other downstream users, if any?) can lower it under `TargetPassConfig::addIRPasses` for example.
