I’ll ping @fradamt but I might have misled terence here, aiui PTC is not enough when the execution proposer is not chosen by the beacon proposer of that slot. SSF works but so does “two-slot PBS” with two actual attesting rounds

Have to think about it more, but the rough idea is that, if an execution proposer is not chosen by the previous beacon proposer, it is even more important that they be able to deliver their block regardless of what that beacon proposer does.
