"I can see an awfull lot of awkward and pride destroying sessions in the sim coming up if 65 becomes the norm. Not easy to take someone to one side and say "no more", pretty rare now but not in the future I fear."
You make a very valid point. Starting your retirement unexpectedly as a result of a failure in the sim could be a very bitter pill to swallow. Most pilots I know take a great deal of pride in what they do and if your competence has degraded without your noticing it, it could be very tough to be told, as you put it, "no more".
Having said that I still find an arbitrary date to be illogical in determining your competency.
