Based on what is said in sections 220.127.116.11 and 6.5.5 I don't share
your view. It seems to me the manual is clear, if an ISP assigns
a /48 to someone then it must be registered via SWIP, with the
possible caveat of 18.104.22.168 which allows for the customer name to
be replaced with "Private Customer".
I don't see anything that would make this not true if the assignment
was done via DHCP-PD.

Let me assume your previous interpretation is right. A /48 assigned
via DHCP-PD to a cable modem customer (as an example) is not required
to have a SWIP entry. However, a /48 assigned statically is required
to have a SWIP entry.
How does that make any sense? What if I make the DHCP-PD "static",
e.g. enter the MAC and prefix in the DHCP server, so the client
always gets the same range. Does it now qualify for a SWIP entry?
In IPv4, it's highly likely that a megacorp (GM?) will have something
larger than a /29, and have a SWIP entry. It's also highly likely
that a person (residental customer) will have something smaller
than a /29, and thus not be SWIPed. As IPv4 scarecity continues,
this is likely to be more true.
In IPv6 that's not so. The megacorp can likely live in a /48. A
residential customer is just as likely to get the same /48. The
old probabilities don't apply anymore.
In case my position, in both IPv4 and IPv6 was not clear, I believe
* No residential customer should ever have their personal information in
WHOIS for any reason.
* Contact information in whois should lead to the entity /most likely to
help/. I am extremely skeptical that putting folks as wide ranging as
Grandma to many small businesses is going to lead to that result, I
think in almost all cases their upstream ISP is a better place to go.
* ARIN should devise policies and procedures such that it requires the
minimum level of effort for an ISP to comply.
Rather than have millions of /29 records in the database, I'd rather see

Where the usage data was updated on some periodic interval, perhaps say
It protects peoples privacy, provides usage information ARIN needs and
makes it visable to the community, directs people to contact information
that is likely to get someone who can help, and greatly reduces the
burden on the ISP and ARIN to process tons of SWIP templates, 99% of
which just say "Private Customer" and "Private Residence" anyway.
