I don't think the distinction you've tried to make is either useful or practical. All it seems you're really after is a way to bring back a Morse test to keep folk out of your favoured parts of the bands. Those days are past. Let go of them and look to the future. Look to the training and mentoring of new operators. Look to encouraging good operating standards. Put effort into leading and encouraging, and folk may come to respect you and follow your example. Spend your time complaining and trying to impose restrictions, and you'll find yourself in the GOOF (Grumpy Obstructive O.F.) bin.
