That's an interesting thought. In the absence of working back annotation, it's not uncommon to see something you want to change in the layout, go to the schematic to make the changes, then forward annotate the netlist update and see the changed rats. I recall using systems with some level of functional back annotation where "simple" changes like which of the 4 gates in a 7400 series gate package were used where could be trivially updated in the schematic just by changing the section designation and letting the resulting pin number changes ripple. I can imagine how the changes I personally am most often making, which are pin choices on SOCs or connectors, could back annotate fairly cleanly. But I've never personally seen a working system where more complex / arbitrary changes were able to be back annotated in a satisfactory way. So I suspect there's some hybrid approach where simple things just update and more complex things fall into a "hey, human, you figure it out" path could make a lot of sense?
