Oh, as pilots (hardly ever happens) we do not mind taxi airplanes for maintenance.
By being called from home or hotel to go to airport, we get credit for 3 hours flying.
With Aerolineas Argentinas we have two dozens of mechanics fully qualified to taxi airplanes.
We sometimes get these guys in simulators to qualify them to run the systems correctly.
Some can taxi all types, some can only do certain type of aircraft.
The only thing they cannot do is high speed runs on the runway - for that they need a pilot.
