I would note, it's not too late to fix these problems.  We
don't
have wide spread IPv6 deployment yet, and I can't imagine
it's all
that hard to send a default gateway in DHCPv6, for example.

Someone earlier threw out an offhand 'preferred gateway'
DHCPv6
parameter as a possibility.  This is actually a nifty
idea...

"Hey, you there, use potential gateways in the
following order!"

It has the same utility and simplicity that MX records do.
