Uh, no. The *only* loopback address is ::1. The rest of 0000::/8 is reserved. If you have a loopback software interface, you could set up a link local address like fe80::1, but now your DNS software has to understand link scoped addresses like fe80::1%lo. Having set up a DNS cache on my LAN using link local IPv6 addresses, I can report that it doesn't work very well. All in all, I think the advice to stick with IPv4 loopback addresses is reasonable. We can revisit this in 2050 when IPv4 is starting to be phased out.
