what do you expect non-dynamic servers to do in the presence of ANAME? i 
assume you'll recommend that they also host real A and AAAA RRsets at 
the same name-node, which only a dynamic authoritative would ignore?

if so, there's a third work flow available, which is to use RFC 2136 
dynamic update to periodically update those "last resort" or "static" A 
and AAAA RRsets, for a non-dynamic server.

and if so, why aren't we just specifying that, and avoiding the creation 
of a new kind of authority server ("dynamic")?
