WR's sarcasm notwithstanding, the tradition of walking off from all climbs is a feature of a past that is not ever going to return, and no one, certainly not I, am suggesting anything like that for the present situation.
This does not mean that there might not be a few selected climbs where walking off is as fast or faster than rapping and, given all the things that go wrong with rappels, safer as well. For such climbs, walking off is a matter of intelligence, not tradition, and that is the only context in which I have advocated it.
I might add that as far as walking off goes, the Preserve is not a fan. They are basically pleased with the substantially lowered stress on the cliff top brought about by rappelling. Of course, that lowered level of stress was traded for large impacts at the cliff base, but it may be that the base was a lost cause the minute parking on 44 was banned.
Given that the level of crowds at the Trapps, it is in all climber's interests to manage the traffic flow on climbs. The worst situation, in terms of safety and usage, is to have people rappelling back down the climbing route. If the ability to do that includes anchors that can be used to monopolize first pitches for top-roping, then the situation is that much worse.
Rather late in the game, the Preserve realized that they should have focused their bolting program on creating separate rappel descent routes that would not interfere with climbs. If such descent routes involved short cliff-top walks, that would be acceptable. There are now a few such routes, perhaps not enough, and they are certainly used, but also probably not enough. People will install slings on a tree rather than walk 100 yards to a bolted rappel route.
Climbers have not, in general, shown any inclination to view the environment in any perspective beyond their most immediate desires, and so have created and continue to create their own rappel anchors wherever they feel the need. It would be hard to argue that the Trapps are not over-supplied with rappel stations at this point. Some are dangerous, but many are just redundant. Those in the middle of perfectly good climbs, occasionally in the middle of perfectly good pitches, that tie up the first pitches with top-roping and direct traffic down on top of other climbers are the worst.
So there is certainly plenty of room for paring down the rap anchor weeds, it has nothing to do with old farts pining for the traditions of a lost era, and trying to make it seem that way is just fiddling while Rome burns.
