WRT IPv6 can we solve this by requiring all fixed IPv6 customers
(still allowing residential privacy) to SWIP, and allow dynamic
customers up to (and including) /56 to only SWIP the parent
block to the residential market?

We would need someone to come up with a usable definition
of fixed and dynamic...

Any statically routed network is considered fixed.

Any network announced by a customer to a provider
via a routing protocol is considered fixed.

Any network provided by a provider to a customer
with the expectation that the address will not change
is considered fixed (even if dynamic mechanisms are
used to provide the address)
[excluding re-terminations and divestitures]

Any network with a customer specified ip6.arpa address
is considered fixed.

Only networks provided by a dynamic mechanism such as
DHCPv6 with a sufficiently short lease such as 1 year or less
and no customer expectation that the address will persist if
the lease times out may be considered dynamic.
