It's probably going to need to be reset before EVERY layer that's being redone, I think, right?

Not sure about what you mean, but my answer is probably "no".
Let's say your Gcode is as follow (2 layers being redone):
layer n-2
E42
layer n-1
E50
Pause
G92 E42 --> that's what the fix does
layer n-2
E42
layer n-1
E50
Basically my code browses the n layers being redone backwards, finds the first one to be redone, get the extruder position, and resets to that value after the pause.
Gcode with 2 layers being redone to prove it "works":
Before, we had this behavior:
layer n-2
E42
layer n-1
E50
Pause
G92 E50 -> position was reset to last extruder position
layer n-2
E42 -> Retraction !!! (50-42)
layer n-1
E50
