-That- isn't what I mean. I was writing about -names- not -systems-.
Take a dual-stacked system that does www:
www IN A 10.2.3.4
IN AAAA fe80::1:2:3:4
www4 IN A 10.2.3.4
www6 IN AAAA fe80::1:2:3:4

If it were a sufficiently well-known, reliably-present work-around for
dual stacked systems I would expect users that know that their networking
is partially broken to learn about it. It's sometimes amazing how fast
workarounds travel if they actually work :) (which would mean no
reference to the site name in the pages so site-internal links work
for www, f.e.).

If all of the networking works, I think nobody cares. But if one type
of protocol does not work, having a more elegant way to work around it
than digging for the address type that works and inserting that in URLs
might be useful.
