Like I said, the plan for that one was to just use the Attributor's `getAssumedUnderlyingObjects` to interproceduraly identify pointers with a common address space. We would then let the existing pass handle intraprocedural propagation. I'm not sure if that's an explicit replacement for the functionality proposed here. I think @jdoerfert wants to have address space deduction available inside the Attributor regardless, so we'll probably get that working eventually anyway. I don't have a definite timeline on this, but I could try to implement it sooner if this is important.
