I'm not sure....

If the user asked for a 2-ply evaluation I think he deserves to get one.

However, when gnubg makes his moves during a match, your suggestion
makes sense, since gnubg just have to select the best move, not show
detailed analysis for all moves.

As I understand it, this is exactly why Joseph doesn't like the move
filters for analysis (or "hint"). For analysis (and possibly also
"hint") I would expect to see at least two moves evaluated on the
highest ply so I can see the difference between the best move and the
second best move, and you really can't compare a 2-ply evaluation of 8/5
6/5 with a 1-ply ditto of 13/10 24/23.
