Right. Anyone is free to experiment with changing read-regexp today. I think a combination of rx input with paredit* for easier editing might work pretty well, maybe with a mode key to distinguish input modalities. (Which gets me into more about how isearch should have multiple orthogonal modes sharing history, not a hard distinction between the literal and regexp cases.) * or whatever structured editing package people use today
