It's a tough issue. On the one hand, I can see how having bolts on top of the first pitch of the stairway would be ok. After all, like Mike said, it gets tons of traffic, and it's much safer to have those bolts there than to have people always chopping holes in the ice to belay from. I also like the idea of being able to go there without hassling you REAL ice climbers to take me and do all the hard work for me (like setting up anchors).
On the other hand, I agree with sunny-d as well. I would hate to see this sort of thing spread to other climbs. For example, if I saw a bolt on top of some boulder problems in little, I'd be pissed. (reminds me, there's a bolt that I still need to fix out there). To me, the actual physical aspect of climbing is only half the fun of climbing. The mental aspect of committing to a climb knowing it could hurt you, and scaring the shit out of yourself, is the other half.
One other question I had regarding the placing of bolts on ice climbs. I recall hearing about issues with bolts in particularly wet areas, such as Thailand, in which even stainless steel bolts get corroded very quickly. I wonder how much of an issue that is with bolts that, for 3/4's of the year, have water running over them. To me, that could become an even bigger safety challenge. How many people are going to go up there and set up a toprope without looking at them to see if they need replacing?
