What I found interesting is that the definition of a CBO is expanded to include, among others, that one "...provides assistance and support in the development and operation of locally designated model aircraft flying sites." (pg 217 line 21 through 218 line 15).
Now, given that AMA tells us they are already recognized as a CBO (per Chad B.), why would they want this added? Perhaps to make it more difficult on competitors to compete for membership dollars?
