hard to debate with ya there oldpilgrim. take it a couple more steps...
taking a tad further. engine braking when going down hill, with a trailer behind you. and you are trying to reduce amount of speed you pick up going down the hill. so ya don't end up having a "run away machine and trailer".
HST or manual / geared tractor? HST = some internal leakage of hyd oil, resulting in less braking. vs a manual / geared tractor.
how many semi truck drivers when in the mountains / taking long steep slopes, down shift, to gain some engine braking? vs relying in regular brakes to keep the speed down?
================
overall "grunt power" and running in to high of a gear.
HST, when ya load them down (run out of torque and still have traction), the relief valves kick in. running the temperature up of the transmission oil, not many tractors that i am aware of, come with an actual temperature gauge just for the transmission oil. so ya do not boil the transmission oil / cause the oil to deteriorate much more quickly.
a manual / geared tractor, if ya load them down, a tall tell sign, is the engine will bog down, perhaps to point engine dieing.
a HST, you do not get any sort of warning lights, or singles, of relief valves opening up. and not letting you know that you need to pick another lower gear.
