I think patrick, while working for an evil capitalist company true,
still does care what happens to the routing table after he stops
caring about money... He's been around for quite some time and is a
smart fellow. Things like shim6 and PI in v6 are very hard sells to
operators of the networks that make up the Internet today. There is a
reason for this, which Patrick outlined... ignoring that seems silly.

stopping the PI train is hardly a simple matter. I agree that failing
some reasonable 'multihoming' solution in v6, v6 is dead on arrival. I
don't see that PI space is a smart move for the long term though :( If
PI space gets final approval it will mean that all of the DFZ
providers will have to carry all (or nearly all) /48 routes for
eternity... There is no way to get back the /48's assigned under PI
space after a multihoming solution that makes sense arrives, and there
is, honestly, no driver to continue working on a multihoming solution
now that there is PI space.

Perhaps the original architects of v6 thought that by not proposing a
multihoming solution, multihoming wouldn't happen? or that someone
would arrive at a better solution than smaller deaggregates? Who
knows...

because ipv6 was so profitable for them so far? most don't even do v6
correctly today, after 10 years of development! We are in a very bad
position on all fronts here, shim6 isn't making it better, PI v6 isn't
making it better and vendor's doing half-baked product deployments
aren't either.

it seems that backing up, restarting the 'new protocol' process is
likely to end up with another 10 years wasted, so it's very hard to
see a reasonable path forward at this time.

I doubt patrick cares so much about whom they give money to... I think
the real issues is if the network will survive in it's current state
with more routes added to it?

actually, take this up with the original designers/architects of v6...
the decisions made then are why we are here today. :( vendors are
evil, mostly, but they aren't fully to blame for this plight.

you have some basis for this? I don't have that same faith... I think
that quite quickly every entity that has ipv4 space will have ipv6
space in some PI fashion (if they have ipv4 PI space) and we'll all be
stuck routing that and more from now until eternity. That will
effectively double the current route table, which on much of the
deployed networks isn't such a good plan.
