That is not quite what I said.

I'd be happy to see a more detailed schema that is expressive enough to 
indicate where the stop line is, the physical location of the signals, 
which signals are in sync, how many signals on a journey, etc.

The current one tag/independent node system means that you need to make 
a choice in what you can represent.

Since I can't see a way to generally and accurately represent traffic 
light count in the current schema, I think that is the wrong choice to 
represent just on dual carriageways.

I think a relation that links these nodes is probably inevitable.
