Something in the sort of what has been addressed there, yes.

Just that the solution shown there works only for lists of scalar
elements.  It doesn't descend into elements and thus cannot find
elements that have evolved differently in .emacs and the default.

And even if I had a solution for that I would need a strategy for when
and how to apply it and how to revert from earlier applications.  Users
are expected to read NEWS and run `customize-changed-options' whenever
they download a new version of Emacs.  Apart from that they are
completely on their own when dealing with options whose value changed.
