@pravb I disagree that this would be an uncommon client use case. It's important to distinguish migration from multipath; the former does not imply simultaneous use of two interfaces, just a transition between interfaces. This is exceedingly common on all mobile devices (moving between Wi-Fi, LTE, and back again), and even quite common for laptops that get plugged into Ethernet, and may be unplugged. The lack of support for resiliency at the transport layer has plagued many connections.

I agree that if there *is* an option to be negotiated, it should be an explicit disabling of the feature, and we should assume that migration is enabled by default. Opt-out is fine, opt-in is too limiting.
