Your view of how bugreport.apple.com is to be used is flat out wrong.

Let me just copy part of the topic in the #iphonedev IRC channel (which was set by a DTS engineer from Apple)

FILE A BUG! YES, FOR EVERYTHING! (https://bugreport.apple.com)

Apple DOES want you to use the bugreporter to respond with feedback. The bugreporter is the ONE and ONLY way to do this officially. When a developer files a report through the website, it goes into Apple's internal Radar bug tracking system to be dealt with. Feature requests, enhancements, and yes bugs all go there. Radar is institutional memory for Apple and a way for managers and engineers to figure out what to work. If a rash of developers file reports related to the same thing, that gets the attention of management and leads to it being addressed.

So what's in it for RA is for the ability to voice concerns they have with the development environment. Do I agree with all their issues, no. Do I respect their right to do so, yes. And I encourage every other developer who has an issue of any kind to do EXACTLY what RA is doing.
