If I might hazard an educated guess about that, it's probably because on JustJeff's page about ring buckles he says that the CC buckles:

'were kinda tough to loosen when I pulled them tight, they took a bit longer to set up than the rings, and the webbing had to be removed each time...so there were two extra pieces to keep track of'

For all of us 'copycat' hangers, that's a pretty strong recommendation. Also, it's pretty easy to acquire/assemble this mod, hence the popularity. That's my theory.
