I think that this is a really good goal. I can identify the following
that probably need work as part of this to improve the user experience.

1) For a user, there is no option in NetworkManager to enable dhcp6c
from the gui. By Default, this option is "not listed" in ifcfg-ethX,
even as a DHCP6C=no, making it hard to find and enable. 

2) Privacy extensions still has no UI to enable / disable from
NetworkManager.

3) dhclient prefix delegation often has issues on pppoe sessions,
meaning that you will often get the pppoe session dropping out, ipv4
will recover correctly, but ipv6 will not re-request a prefix until some
timeout, usually an hour, in which time all ipv6 services are
unavailable. This causes DNS timeouts, webpages to respond slowly, email
accounts to not fetch etc. 

4) For link local to work "nicely", mDNS name resolution should be
installed and available by default. Avahi can provide such a service for
ipv6. 


Perhaps a good way to test this, would be to try and run a system or
network as "ipv6 only", as that will quickly identify short comings of
the system.
