It runs contrary to the "spirit of C" to require the implementation to
generate code that does operations the hard way when a more natural way
would suffice.

Personally, I would consider the "quality" issue as being in the opposite
sense:  Trapping on invalid address manipulation would be beneficial in
my view.
