This is a handy feature when the user wants to see what's coming up on one specific channel over the next week. It would be nice to have it available on the client if possible, but I'm not exactly sure how to do it best with the current GUI. I'll bet you guys could come up with something really slick, though.
In my use, Sundance and IFC have a pretty fair selection of movies that come up throughout a given week, and it's nice to be able to casually see a whole bunch of it on the screen at one time, for just one channel. Not super high on my priority list, but a useful thing none the less.
I suppose this is technically a feature request that I would vote for.
