Continuing to use the status quo notation would hardly constitute driving the bus off a cliff. And the cases of microtonality are not that edge. Beyond allowing interoprability among musicians from different cultures, western notation has been critical to most (and there's a lot of it) western microtonal music.

Who the hell cares? Use a different notation for the .00000000001% of the time you ever have to interop with a non 12-tone equal temperament scale.
