Indeed.

I came to the same conclusion myself a while ago.

We all came up with IPv6 scalable multi-homing solutions that were more
or less complex and more or less workable. Some of us acknowledged that
there was no single solution, and all of us acknowledged early in the
game that the solution we proposed would not be as simple as IPv4
multi-homing.

I realize now that this is where we erred: by shifting the multi-homing
problem from the ISP to the end-user, we made a less-palatable protocol
that is adoption-challenged.

We forgot to KISS. Mea culpa.

Michel.
