I would love to see this happen. It would be an awesome tool for backend development and testing.

Realistically, regressing backend bugs barely show up on the radar. We seem to be much better at inventing new bugs than at making the old ones reappear.

If we ever start playing whack-a-mole with old bugs, this will get a much higher priority. Grease the squeaky wheel and all that.
