I agree with this direction, but want to point out that P-high are retriaged every three weeks, and we are cycling through P-medium as well, so they are retriaged regularly.
I will post a thread to irlo suggesting we create release milestones, and define them as 'must fix right now'; and defining P-high as high-priority per team opinion; both retriaged every 2 weeks in this meeting.
Once complication with this use of release milestones is that the roadmap RFC may end up also using release milestones for estimated goal completion. This means it would have two purposes - critical bugs, and tracking non-critical but expected features. I'm not sure this distinction will matter much as long as we're continually retriaging them.
I have bumped triage frequency to every 2 weeks.
