I watched a presentation online by a large software company who used to to do this. They deprecated this as "prioritization by whoever shouts the loudest". Once a crash-bug-reporting system was in place it simply went away, as they had accurate enough data on how many people were affected, and could prioritize based on that. This won't help if it's not a crash bug, but the criticism of "prioritization by whoever shouts the loudest" is still valid.
