We are doing research in this area.  The idea (as we are trying to
use it) is to be able to judge similar positions as having the same
value (or close to it.)   With a detailed analysis you can prove a
small search will not return a score significantly different than
a related position.   There are a lot of interesting ideas to be
exploited.  I believe Deep Blue has also experimented with this and
may even have implemented something.
