I fly only at home so accessing the computer is no big deal to me, but I could see if you travel to some place where you don’t have access to a PC that would make complete sense.
I have a feeling that the transmitter has precedent over BetaFlight. The reason is that BetaFlight on your flight controller will not see the throttle position until the receiver sends the data over.
So let's say your physical position of your throttle stick on the gimbal is at perfectly centered mid stick. You are using a throttle curve on your transmitter saying that at mid stick your throttle should be at say 40% instead of 50%. Translating to µs. If your throttle stick at 50% is 1500 µs. Say 40% is 1400 µs. The receiver will send the 1400 µs data to the flight controller. Then the BetaFlight firmware on the flight controller will determine where it should put the 1400µs pulse on your throttle curve within BetaFlight.
So no BetaFlight does not have precedent.
On and one more item why I don't use throttle curve on BetaFlight. Say if my quad flies at throttle setting below 50%. I set a throttle curve like an exponential curve on BetaFlight. Then I set the offset to mid stick at below 50%. I believe what I saw was that the throttle curve never reached 100% if I off set the mid point.
Also Betaflight only set the throttle curve as an exponential curve. When I set throttle curve on my transmitter I set it as a 9 point curve.
Another reason is that an electric motor or a wet fuel reciprocating engine do not have a linear power output band. During the early days with RC helicopter we try to fly at a constant rotor head speed as much as possible. So we tweak the throttle curve to adjust to the load of the rotor head to keep a constant rotor head speed. That is quite a different animal since the single main rotor helicopter usually has collective pitch mixed in with the throttle stick.
