The main problem is not zunzwangs but cases when the null move pruning prune line that has a deep threat. I also believe that extensions are important and 15 plies with the normal extensions may be better for analysis than 16 plies when you tune down extensions and razoring. If you want good analysis of the position the best thing to do is to ask the top programs to use a long time and not to goto big depth. Uri
