In my opinion...
Leave /29 alone or change it to "more than a single IP address." In these
days of IPv4 shortage, substantial networks sit behind small blocks of
public addresses. These networks should be documented with reachable POCs
lest the anti-spam/virus/malware folks slam down /24 filters for lack of
information about how misbehaving networks are partitioned.

Change this to "more than a /56." Service providers should NOT be assigning
/64's to end users. If you're doing that, you're doing it wrong. An IPv6
customer should be able to have more than one /64 subnet without resorting
to NAT so /60 should be the absolute minimum end-user assignment,
equivalent for all intents and purposes to an IPv4 /32. If we then want
"equivalence" to the /29 policy so that individuals with the minimum and
near-minimum assignment do not need to be SWIPed, it makes sense to move
the next subnetting level up. In IPv6, assignment is strongly recommended
on nibble boundaries, so that means /56.
