I don't know, I think the application supporting more than one address
returned for an A or AAAA query is one step closer to the current
century.  Having them magically get an ordered list of A or AAAA records
seems like an overall win to me.

The real problem comes in when "just try the first address" applications
meet "SRV wrapper."  That's where the real annoyances lie IMHO.  Random
failures, random different performance... but you get that anyway I suppose.
