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
