The answer is YES, and this type of shifter is a favorite among mountain bikers whose reliability needs and "field conditions" are already much more challenging than your average biker.
There are plenty of examples of situations where a wireless setup simplifies things.
I used to put wired speed/cadence sensors on my bike. Now I just zip tied two BLE gyros to the wheel and crank and things are vastly simpler. I've had them there for years and still haven't changed the battery. I've also never tangled the cables or had to fiddle with the mounts for a magnetic sensor.
