The sort is demonstrably a loser for smaller indexes. Admittedly,
if the index is small then the sort can't cost all that much, but if
the (correct) threshold is some large fraction of shared_buffers then
it could still take awhile on installations with lots-o-buffers.
The other side of that coin is that it's not clear this is really worth
arguing about, much less exposing a separate parameter for.
