I don't think there's ambiguity about what an dotted-quad without a

something?

Classful addressing is still part of many user interfaces, for
instance Cisco's IOS.  It's not just that the CLI accepts it, it's
also the standard[*] output format (that is, "192.0.2.0" instead of
"192.0.2.0/24"; if no prefix length is given, the one based on the
class is used).

Again, is this at all ambiguous *in the context of a host IP*? (IOW, if I say that I recieved an IP packet from 10.0.0.1, are you really going to ask me to clarify the netmask?)
