We ATC do not need POB and FOB, the fire fighters are.
That is certainly true in specific kinds of emergencies--those that threaten to quickly end up on a runway somewhere--but there are many other kinds of emergencies, sorry maydays, where SOB and FOB are determinants for different reasons. Which I say not as "a nonprofessional" but as somebody who made his living flying GA aircraft. We aren't all airline pilots.
