        TCA: Topologically-Correct Address, for Gateway.  It can be
             manually configured on Gateway, or DHCP, or stateless
             autoconf.

Yes, it could. But in that case we should come up with a means for
Gateway to obtain not only a TCA1 from the Internet but additionally an
entire prefix. Out of this prefix Gateway could form its G4 and put it
in RA, and finally Router forms its G address (TCA2 let's say). Without
that prefix Router couldn't get a TCA2 from Gateway.

(Now I realize that by "G" and "TCA" we actually mean the same thing; we
should use just one.)
