I believe the complaint isn't about what _can be_ done, rather what
_is being_ done.

I've always wondered why they made a single "address" field if the
IPv6 architects really wanted a hard separation between the host
identifier and the network identifer. Making the "address" a
contiguous set of bits seems to imply that the components of the
"address" can be variable length.
