but I’d rather wear out the brake pads (relatively cheap) than the clutch or gearbox (relative not cheap)
Engine braking doesn't use friction. It uses air pressure to resist the cylinders.
You're missing the bit with involving the clutch and the engine revs before they're slowed.
I'd still rather wear brakes than clutch. There's no free lunch.
