I'm still fairly ignorant about the whole rrd interface, but doesn't counter support also require us to have more flexibility in declaring the RRA(s) per RRD? Of course, basic counter support would still count to one instead of many, but if the strategy for determining "counter- ness" is to provide this information in meta-data attributes other than "type", perhaps counting to many is called for.
