I think this could be useful when syncing a reverb to a track, because then you could just turn the controls so (for example) the peak of the impulse matches one of the lines of the grid. Obiously you have to fine tune things by ear, but it would save you from doing the math.
I felt the need for a feature like this a few time ago, when I was working on a track that featured a reversed reverb as a special fx for a transition and I needed it to be synced to the track's tempo.
Obviously this is not a deal-breaker feature, it is just a small little function for lazy people (like me!
Perhaps, even if I don't know very well other convolution reverbs beside Reverberate, I think there's no reverb on the market with such feature...
