Yes, I was thinking the same thing when I answered earlier.
I am in the same position as you here (meaning someone who has
contributed some patch), so my opinion doesn't have a lot of weigth; but
as I already said, the feature has some value with the ORDER BY added,
and the LIMIT/OFFSET thing expanded to allow expressions (this last part
is in TODO).
Clearly an ORDER BY clause without LIMIT doesn't make any sense; but
it does with it.
