I recall Shibata Ichiro taking rank away from folks (not to mention the MANY failed tests). I guess they didn't continue to measure up so he dinged them. Not at all like merit badges that are collected but ongoing evaluation and rank according to now with minimal regard for history.
If more did that (taking rank away) then I think things would be considerably different. Think of all the professional groups that have annual, semi or biannual re-certification requirements. If one does not measure up then the door is shown.
I was present at a USAF-WR Camp many yrs ago and watched someone fail his recert as shidoin. It happens.
