There must be more to it than this, because my machine has a "scope
global" IPv6 address, but no default IPv6 route, and everything is
behaving reasonably (IPv6 does not work, as expected, but nothing tries
to use it either).

My ISP is Brightspeed, and my router (provided by Brightspeed) is
running "EXOS Version 26.1.0" according to a tooltip on the router's
administrative web page. The router very clearly says that IPv6 is
"Disconnected" on the first page that I see when I login.
I have done nothing whatsoever to change how IPv6 works. I wouldn't even
know how. This is all out-of-the-box behavior.
For a very large number of people, IPv6 connectivity is still unavailable.
