I have never had a back fire or any stumble due to rail pressure drop. I do wonder how low is too low? 2300/2000/1600? Anyone know?
It only does it down low before 5kish rpm, then the pump catches up through the rest of the gears.

Any drop is bad tbh but from expirience I would say low 2000ish is max I'd be comfortable with and even then it better be rare.
