I may be in fact that that they are not less able to cope.
No, that wasn't what I was talking about. Not "I get a new source address
and need to cope it", but "I have two source addresses with global scope,
tried one according to source-selection rules, it did not work, so I
should maybe try the other one now?"
No network dynamics of any kind involved, just "a normal homenet
multi-ISP scenario" (with some breakage "somewhere upstream", not
something the host can easily see) - I thought that this would have been
obvious from the thread and WG list context.
The advertised IETF solution for "(SoHo) multihoming" is "multiple global
IPv6 addresses", but this does not work yet as well as it could, partly
due to this missing piece.
