I had to hold my nose about the frequent use of sinular "they" in
what your friend sent, but it is very interesting.

I have nothing in principle against switching to an Undo/Redo system.
But there is an obstacle: finding a key for the Redo command.

However, I think this aspect of the behavior is bad:

A good Undo/Redo system should save the states C and D somewhere and
offer SOME way to get back to them.

This might be feasible to implement as an option.
