Well, I was asking about your _particular_ preference, which seemed 
rather clear from your use of the word "crap". Why does it matter (in 
_your_ opinion) if the target of the "www" CNAME owns records of more 
types than just A and/or AAAA?

Also, have you considered the forward/reverse ambiguity that arises when 
multiple owner names resolve to the same address? To which of those 
names does the PTR point?
