Understood (and I have a similar equation written down from my Air Cadet days!).
To trim for G or flight path, rather than for attitude, is to add complexity to that simple performance formula.
Sure - and as HN39 suggests, I think the flightpath in the y axis amounts to "this pitch, at this V/S at this airspeed". The calculations may be more complex, but the intent was to make things transparent to the pilot.
Given that Airbus supplied pitch/power data to pilots from the get-go I think that aspect works in much the same way as it does on other types as long as you stay within the envelope. Even if there were some variation I have a strong suspicion that it would be barely noticeable.
