Subject: [core] More Options

I just had a good discussion with Kepeng about his two drafts.
They introduce two options (response-mode and size) that sound useful.
It is, however, hard to judge at this point whether there are usecases that actually require them.

This reminded me of draft-bormann-coap-misc:
The whole point of that document is to collect information about options some of which sound useful and about which we don't have sufficient usecase information at this point.

So we agreed that it might be a good idea to continue this process of collecting fully fleshed out option proposals (whether focused in a single coap-misc document or distributed over several individual documents isn't important).  This way, we

-- get a better view of the landscape of proposed options, so that we sometimes may be able to find a simpler, more general approach to more than one of the problems.

-- can discuss the design of the option between interested parties without getting entangled in a "do we really need this" discussion each time,

-- can actually implement a couple of the options in some systems and do interop testing so we know how well the design works, and thus

-- have the options ready to be pulled out into a WG document once we do have the deployment experience that would justify their standardization.

I propose that this become the default mode of working on new options for CoAP for the near future.
