Is this something new with IPv6? Because that is fairly standard
practice for IPv4... for instance, if you get a /24 in IPv4, and you're
setting up a router, you might set an IP address from that range on each
interface.
Anyway, since there's no reason why not, I went ahead and made that
change.

In my experience, it doesn't work this way. I've had a lot of trouble
pulling up www.netbsd.org, and traced it to MTU problems. Setting
AdvLinkMTU to 1480 made things work a lot better. I tried 1280 just
now, and that rendered it impossible for me to access *any* website that
I tried.
Thanks for your suggestions and corrections, Joroen. It is appreciated.
