Read the other "no" votes, and I can understand the points made. I noted that neither respondent offered to maintain this feature, but indicated that it had some value.
There really isn't any need to make a decision about this because it will take care of itself. Since no-one is maintaining it (and I really don't have time to continue to do so), and it tends to break easily, this module will "self-deprecate" rather soon. When that happens, we can wait and see if anyone cares enough to step forward and take responsibility for maintaining it. If not, then we can note that support for this feature went the way of other things that died due to lack of interest within the developer community (e.g., xgrid)...which is totally okay since this is, after all, an open source effort.
