Where is such a thing useful?
I think it unlikely to find two kings and 12 pawns on the board.  And 5 piece
tablebase files are common.  So for small numbers of pawns, yet too many pieces
for the tablebase files, it might be very useful information.

Also, since we know we are computing a pawn race, it may simplify calculations.
Because we stop once we convert (or perhaps a couple moves after) it would not
be nearly as difficult as a complete endgame tablebase.
