I understand they're both not critical, but they are used as defaults in Ubuntu.
The definition of defaults it that ideally they should work for all
users, but this isn't the case now.
If the ntp and keyserver would have A + AAAA, then they would work for everyone.

The ultimate goal is that it should be possible to install and run the
OS in a pure IPv6 environment, without any translation mechanisms.

Of course every deployment has its own specific needs.
I have been very enthusiastic lately about our dual stack proxy server.
It provides IPv6<->IPv4 translation and additional security at the same time.
