Your intuition is wrong.
Engines experience issues when changing speeds (especially start-up) not when at steady thrust output.
Fair enough. But delaying engine start-up until the aircraft has nearly finished taxiing wouldn’t have any effect on the way the engine operates during start-up. It just means it would spend less time at idle or near-idle speeds during taxi.
