Thanks for looking into it! Unfortunately we don't have a range of milestones now, so I'll need to come back to this thread when we have. By sending this request early we were hoping that if there are any concerns or action items to do before getting the approval, we'd get to know about them early, and when our partner is ready we'd be also ready to start the experiment. Please let me know if there are any such concerns or action items currently known.
(I added a comment to the requests-for-position about the per-function extension of this proposal.)
