Right.  This is missing in the whole "only bad ISPs will ever give their
customers prefixes that are not stable" discussing - customers *change*
ISPs, and this should be as painless as it is in the IPv4+NAT world.

Thus, anything relying or implicitly assuming "IPv6 addresses are stable"
(in an unmanaged SoHo network) must be very much discouraged.

Maybe even dual-/48 multihoming can be made to work one day (and no, it
is not even working well in theory today, but even less so in practice with
the CPE implementations you can buy today).
