N.B. you will need to tweak IPv6 routing to favor the new dedicated
/64 over the shared /64.

Yeah, it appears Linode implements the dedicated /64 by routing it to
the shared /64 address, so you can't just remove the shared /64.

And unfortunately, for Linux distributions that use NetworkManager
(which is probably most current releases), NM changed which v6 address
is "preferred" at one point; in old versions, it was the last specified
address, but then it changed to the first specified address (which
probably makes more sense but was still an annoying change).
