In traffic school we were introducted to the concept that a problem intersection that needed a traffic signal, but you couldn't afford a Signal light, still needs a solution. That while a Stop sign might not be as good of a solution as a traffic signal light, the stop sign was better than Nothing.
Failing a "central nervous system" organization, or even anyone organizing such an organization, the loosely connected Historical organization are all that you have got. A poor solution is better that waiting for one you do not have.
