I'm with you Roger.
The tie in to the USGA and R&A is good in ways but bad in others.
The USGA sets up the Open courses in such a way that many of them seem to be pretty similar to each other. The biggest exception will be Pebble Beach when it comes to the game. Shinnecock Hills, Pinehurst and Winged Foot will look a lot alike on WGT.
In terms of the British courses, all of the have a similar look and feel.
My view is that once we have 3 links courses and 5 or 6 USGA courses, it might be the time to hit some of the PGA courses, both the tour courses and the one that the PGA Championship is played on each year.
Variety is what will win out in the end. Sure we all like to see the famous courses that we might never get to play in real golf, but throw us some others as well. 2 courses each year, a tru golf course and a CTTH course should be the norm. Also all new courses should have 2 sets of pins, that is almost like adding an extra courses for very little money.
