Very true and the Transition Altitude in many areas of the UK is now 6,000' and not 3,000'.
.......and 'Selective Availability' has not been a function of the NAVSTAR/GPS system since May 2000 but there are still questions on it in ATPL Radio Navigation, as there are on many defunct and out-of-date areas.
I could quote many examples but the point I'm really trying to make is that the OP stated he was preparing for a PPL exam - it takes the 'competent authorities' a while to catch up with the real world so it pays to stay on top of apparently redundant topics until you know for certain that they're not going to be in the exams.
