In addition to the info you mentioned, appears they moved to cover all the bases.
That is a tad more info and activity than AMA produced.
At this time 100% of my flying will be at a FRIA. But having a RID in the flight box for a possible opportune moment is my choice.
A lot of fellows spitting out YouTube videos saying they "ain't gonna do it" may unnecessarily influence newcomers to the hobby. But, like it or not, it will be the rule for immediate future. It may die a legislative death or one of non-enforcement. Until then the noisy ones can test the FAA but I will comply and go enjoy flying.
