As an ISP: If you don't manage the CPE, should you even care?

yes, yes, being nice is good.  But this is an impossible task.  There is
no way you can make assumptions about the security of any unmanaged CPE,
with or without IPv6.

If you care about the security of arbitrary customer owned devices, then
you should probably start by disabling IPv4.
