I don't believe IETF ever "decided that end users would not
multihome using bgp with multiple ISP's" It was more like they
repeatedly tried to create an alternate method of multihoming that did
not rely on *deaggregation* (LISP, SHIM6, LIN6, HIP, MAST..) in
combination with IPv6 Auto-Config - so that end users could use PA
space to multihome with minimal impact on the routing table and easily
renumber from their provider (as comparatively to v4). But then we
passed the end user IPv6 assignment policy and instantly lost the much
of the motivation to complete that work.

Maybe rather than just listening to what the folks in IETF have to
say, operators should participate more, in order to develop solutions
that are operationally feasible. Be a part of the solution. Much
like the ARIN community and policy development process, there is a
mechanism to participate in the development of IETF standards.
