The whole point of IPv6 is end-to-end connectivity and re-enabling users. Imho something like multi link applications *should* be something trivial to solve in the IPv6 world.
Whether that's PI/PA+LIR space or multiple addresses per node, that's debatable, but generally speaking, IPv6 should be there to *solve* problems, not to add.
I agree :-) "Multiple address per node" + a decent API so *users* can easily control what they want applications to do ("web surfing via DSL, bittorrent on the cable Internet") + proper source address failover would be bliss... Especially "proper source address failover" would be much more robust against remote failures than "BGP" - think "packets going out via ISP A, and there being a blackhole [think broken MPLS tunnel] between ISP A and ISP X, so packets disappear" - with BGP you basically need to fumble on your route policies then. With "mmh, ISP A source does not work, let's try ISP B source" things can be fixed from the application/client OS level. Alas... nobody really interested IETF-side or OS/browser-side in working on that. Much more important to waste energy with stuff like DoH...
