No, it would just be useless noise that would confuse most people,
especially since the default behavior varies across AMs. Please observe
that not one single one of the contrib modules has any occasion to
specify non-default amprocleft/right --- that should give you a fix on
how useful it is to worry about what they are. If it weren't for
binary-compatibility kluges we wouldn't need the ability to specify
these at all.
But I can read the handwriting on the wall: if I want this done right,
I'm going to have to do it myself.
