It is a *logical* idea. Imagine if we didn't have the legacy baggage of pulling cable to downshift in the back. Wouldn't it make more sense if both front and rear derailleurs did the same (upshift or downshift) if a particular action was actuated (such as pull or release cable)? With rapid-rise (or Low normal), Shimano was just harmonizing front and rear derailleur actions so pulling cable (with DT, thumbs, barends & STI) will all result in upshifts. Sounds pretty logical to me and it should be easier to teach newbies too.
I also seem to recall that one of the technical reasons for rapid-rise was to improve rear shifting. Apparently, the downshift-facilitating ramps on the HG cassettes work better when the chain is gently prodded by a spring, rather than getting ham-fisted with an overly eager rider. In any case, it's not a particularly hard skill to switch to. No shifts are truly critical for non-pros, so a mis-shift here or there isn't bad. One can always harmonize all Shimano-equipped bikes with rapid-rise rear derailleurs! :) Anyone remember the reverse shifting Sachs *front* derailleur?
