The reason is that if a host attaches to a LAN and soon afterwards
leaves it, otherwise the autoconfigured addresses by default stay for
a very long time. This confuses people and more importantly, usually
messes up default address selection so that the mobile device will try
to use a wrong IP address.
Some more discussion here:
I think this is in most cases definitely a better choice
operationally. If there's a standards compliancy concern wrt changing
the default values, I can bring it up and ask opinions in the IETF.
