Yeah, it's pretty useful, at least in as far as v6 is useful yet.

You should consider using the automagic (BGP anycast) gateway address
(2002:c058:6301::, see RFC 3068)

Pretty much "shake my head in disappointment and give it up as too hard".

It's not the gateway that would do it; the address in question is the
v4 address embedded in your 2002: (ie, your stf interface); the
public gateway provides connectivity from 2002: to the rest of the
real v6 net only.

The best answer I can see for how it might be done takes that address
and uses its v4 delegation to imply a v6 2002: delegation (since
they're the same ownership by definition), but I see no implementation
of that appearing at the other end of any 2.0.0.2.ipv6.int. NS target.
Maybe its coming, I've stopped paying attention; sure seems like you
didn't find one though.

*shrug* It seems to be blocked on politics, in the argument that its
absence is an incentive to migrate fully to 'real' v6.  I see
disagreement and the argument that its just as much a disincentive to
even start, if anything, but that's politics for you.
