If I understand the purpose of this experiment it would be to provide ADs some indication of level of interest and ability to succeed. I see no reason why we need to formalize this within the IETF. Furthemore, the terminology is problematic. We are overlapping a term that is commonly used by the ITU the way working group is used by the IETF. Let's not make the process any more confusing than it already is. Finally, milestones for such "study groups" seem to me inappropriate. It may be that a topic is uninteresting for quite a while and then picks up. ANY way to demonstrate that interest and ability to succeed should be sufficient, regardless of how much time has passed.
