NPTv6 to the rescue for non-renumbering across static ISP PDs that changes
when ISP *itself* is changed (rather than prefix within the same ISP). I'm
pretty confident people do not change ISPs per 6 hours or per 24 hours etc,
as is the case with the lease time on the dynamic prefixes to begin with.

Not sure what you mean, mDNS and friends, does not care about changing GUA
or ULA prefixes, it operates on link-local addressing and does not work
inter-VLAN anyway (without hacking using mDNS Repeaters/Proxies because
link-local) — maybe I missed something here?

I do agree that those 0.001% of people that SSH into their home

Are you a gamer, Gert? Because many end-users are (myself included), and if
the games they play use IPv6 and works P2P native (we intend to have IPv6
for every layer 7 application, I hope), RIP (literally) to the player, when
the genius ISPs flip the prefix on a live-session — same impact as the SSH
example.

Do we really need to create a list of everyday applications (beyond the so
called 0.001% SSH users) that'd be impacted by dynamic/ever-changing 24/7
prefixes? I'm sure you got the point.
