One other point i would like to throw out is how this will impact lifetime status down the line. Due to higher cabin bonuses etc, after a number of years for people this could put a lot of members including myself closer to GFL for those that don't have it - but at an accelerated rate.
I'm sure they would catch onto this soon enough and move the goal posts there by increasing lifetime thresholds as soon as most of us close in again, because there surely must be plenty of people that will benefit from the legacy conversion
