It's not the engines themselves that need reving. Larger commercial
vehicles (and they don't have to be that large) require the engine to
be revved for several minutes following starting to allow the air
pressure used to operate the air brakes to build up to high enough
leve. Such vehicles have a pressure gauge with a red area on it.
Driving such a vehicle with the gauge in the red area (i.e. without
brakes) is generally considered to be a bad thing. In addition the
parking brake is usually air operated as well and won't release
unless the pressure is high enough.

if you need to do this then your vehicle is unfit to be driven on the
road , the air system should not lose air to that extent overnight


Nonsense. In fact it is (or was when I was a lad) SOP to bleed the air
tanks empty at the end of each day, at least in winter. If the driver
forgot to drain them they'd be frozen solid by morning. And then the
lorry would be immovable and we'd have to get the blowtorches out to
thaw the tanks so that they could be bled and refilled. All the time
wishing we could use the blowtorches on the idiot driver's arse instead
