Are you responding to my mail, or one earlier in the thread?  I stated
that everything should be reverted to before each incompatible change.

Yes, like this.

If you are referring to my mail, I can only assume you are referring to
the last example sequence of edits I gave, and you assume that C’s edits
are dependent on B’s incompatible edits.  C created a completely new way
where there was none.  C may or may not have seen B’s removal of A’s
scribble, but regardless, his edit is a completely new work.
