I'm a bit late to the discussion here, but just to echo what others have said:
South Balconies (including "If We Bolt It") is in the current closure areas, and should not be climbed until closures are lifted (likely in early July). I was just doing surveys on the west side yesterday and there is a prairie falcon pair occupying the "If We Bolt It" area.
In terms of the feasibility of establishing climbs in the other streaks to the right of "If We Bolt It" - I climbed "If We Bolt It" a few months ago, so I'm guessing I have been on that route and climbing in that area more recently than anyone else. I don't recall the hangers being death hangers, but I think at least some were camo'ed. I think the bolts were carbon 5-piece. I found the route to be harder than 5.11a, especially in the crux section in the lower half. There was still some loose rock with chunks flying off in the lower half of the route, so that might account for the available holds changing the difficulty of the route over time. It's a fun route for sure, and very sustained.
After finishing "If We Bolt It" I spent some hours exploring the streak just to the right, doing solo toproping laps on a fixed line. I had thoughts of potentially developing that streak further. I would say it is not a feasible project - the bottom was abandoned for good reason, as there is a section of perhaps 25-30 feet that is exceptionally loose. I could not see a way to clear enough garbage rock to make it viable. It's unfortunate, because above that section, the rock improves near to the quality of "If We Bolt It" and the top half of the streak has super fun climbing, probably in the 5.10d to 5.11a range.
