I think it has a nice flow - better than McKenzie. It might be less popular than you would expect because
Kinley fits the trend more (two syllables max and has ley at the end). I wouldn't guess that the mountain with the same name would be a reason. People are using
Everest which sounds less like a name in my opinion.
