It is, because it causes a lot of nastiness as a side effect.

Most annoying for me: non-determinism, so going to a web page and pressing
"reload" a few times will flip-flop between IPv4 and IPv6 (which, if one
is working and one is not, will make troubleshooting harder than necessary).

Most annoying for people that run large-scale IPv4 NATs: lots of extra load
is put on the NAT that would not be necessary if the client would just do
IPv6.

Microsoft's implementation ("prefer IPv6 if it seems to work to a test 
host") is not without it's own problems, but overall, much less unfriendly 
to network elements and sysadmins.
