Hi,

"Supporting unwilling remote endpoints" is something we cannot afford to
not-do in the next few years.

"Support unwilling applications" is something else, and their time is
running out.  If it can be done on the mobile world, why can it not 
be done in the windows or linux ecosystem?

IPv6-only with NAT64/DNS64 supports the first.

So how many (client) devices do you have that have not been upgraded in the
last 10 years, and do not support IPv6, getaddrinfo(), and friends?

If IPv6 were something new, like "invented last year", that "expect 
devices to be upgraded" argument would be slightly more relevant than
for a protocol from last century.

have you enabled IPv6 on something today...?
