I agree that the primary hostname should have both A and AAAA records.  There
are reasons to have extra IPv4 and possibly IPv6 only records.  The most common
being where some of your services only run on IPv4, having an A record (e.g.
ipv4.yourdomain.com) can prevent delays for IPv6 capable hosts that attempt to
connect.  But the main hostname should have A and AAAA records.

I'm using separate hostnames for binkp and telnet for this reaason.  When I get
around to upgrading the BBS and it can use IPv6, I won't need to do this. 
Similarly, one of my feeds is IPv6 capable.  However, my feed was on a
secondary mailer, which didn't support IPv6 at the time.  This caused long
delays on my end, until he added an IPv4 only hostname, which I switched to. 
The software has since been upgraded on his end, and I've gone back to polling
the main IPv4/IPv6 hostname, now that his end answers on IPv6.
