Err, they do. Here's how to set it up: These balance the load, and if one
machine is down, any browser which handles multiple A records properly will
still fail over to the other machine.

Because its not necessary. Just put in multiple A records, for multiple
hosts which service the same web pages.
(What? Your browser won't use multiple A records? Well, in that case, it
probably will be a much longer time before it supports a new DNS record
type.)
