I'll try and hit each one here...
I dont see how eliminating certification which is education does any good for the organization? makes the intentions of the CDS in regards to training be above reproach. It isn't one agency saying the rest of them are crap. It also eliminates the perception among many certified by agencies other than the CDS that the CDS is for the CDS certified folks.
Because the market is so small and 5 or 6 other agencies certify cave divers who's really going to cave about becoming "accredited" by the CDS? Well you have the top instructors in the world on the committee, lots of instructors like being recognized as "top of game" and it would become that being invited to join the training committee was a great honor.
Wouldn't some be insulted and view it as arrogant to give up a training program yet offer accreditation? There would seem to be an inherent hypocrisy, we're so good we dont need to teach? Some people are already insulted... :-). The people that are in the training committee, those overseeing the accreditation process will all be active and highly respected instructors. It isn't saying were so good we don't need to teach, it's saying that there is a degree of professionalism and expertise that is attainable regardless of agency affiliation and we strive to personify and encourage excellence.
Now lets assume that this happens, how is the CDS going to separate themselves from everyone else? Would offering expedition level mentorships make sense? I'm thinking out load? They already separated themselves by stepping back from issuing c cards, other aspects of the association also take a more high profile face of the agency. Expeditions, mapping projects, conservation efforts, land access, broad based educational efforts (from clinics on cave diving related activities and skills to talking at the local elementary school).
