No, and I'm not proposing to expose ASC/DESC/NULLS FIRST/LAST or
nondefault opclasses (to say nothing of non-btree AMs) or index
predicates either.  The proposed patch is to my mind just a logical
extension of what we have always done --- namely, to pay attention
to index column names --- to some new cases that were never exposed
before.

We could certainly make it pay attention to all that stuff, but I have
the same feeling you do that it wouldn't produce readable results.
And it would make any compatibility issues a lot worse.
