Yep - the result are not nice.
A 397 move 9 point match, 6 doubles, 4 passes, 2 takes, 327 non-forced
moves, analysed at 2 ply (Supremo chequer, World Class cube), with
pruning.

using 0 ply luck analysis it took 461 seconds or 1.16 seconds/move, 
using the same settings but 2 ply luck analysis took 4073 seconds or
10.25 seconds/move.

For what it's worth, here's a comparision of the luck results from the
two analyses:

So the facility is there, but you really want to think hard before
using it.
