I wouldn't mind taking a test as long as it is justified, but no there is a lot more to what I am saying. I'll try to make my thought process more transparent (maybe NCEES could learn from this).
The GA board passed a requirement for the 16 hr SE exam to be the only exam which will grant PE licensure in GA if you open any of the material specific structural design codes in practice. They did this despite any of them having passed this specific exam. There is no need for special seismic detailing in most of the southeast (there is a small portion of Tennessee and South Carolina that is the exception to this rule). The 16 hr SE would never have been implemented in GA had the only structural representative on the board (or his employees/coworkers) been required to pass this exam to maintain licensure. (I was happy staying my little lane).
The ideology behind removing grandfathering is that ONLY new elements that were TRULY needed would pass because the ******** passing shenanigans would have skin in the game at that point. If a change in methodology due to advancing technology or a safety concern is warranted, then it is my solemn belief that EVERYONE should have to prove competency in that new area. Hence why I would like to see these exams broken into further components that you could mix and match to suit your career so to speak. It wouldn't be that hard to do, you could even put the classifications someone has right on the stamp or even their license number for that matter.
In the meantime, without something like this in place, You have asshats out there using the AISC 9th edition and designing concrete with a 1.4DL + 1.7LL load case while passing requirements they don't understand. If your representatives were required to understand these things, I'd be far more receptive to their decisions. In addition, if the understanding for the new material or process was legitimately needed, a form of direction should be given on how to learn the new material or process rather than just kicking you right in the ding ding and then you get to watch them going back to incorrectly using a 1/3 stress increase with current building codes while you've had to basically study an entirely new field on your own because there are either no resources available to you or you have no idea what or where those resources are.
Maybe my ramble makes sense. If it doesn't, I'm blaming the GA board.
