Actually the renumbering problem for IPv6 in home networks is a lot worse than for IPv4 home networks (that never renumber). That's what you get for exposing the home network to global addressing.
I guess it depends on your ISP. When I switched from cable which provides IPv6 to the local telco fiber which doesn't (I'm talking to them about it), I got a HE tunnel for global addresses but my ULAs didn't change.
FWIW, they say my IPv4 address is nominally dynamic but they don't ever expect to change it.
