I'm somewhat neutral on the *need* for this change - a /29 is quite
a huge block of addresses (= only few networks will not be able to
fit into it) and - coming frmo a /35 - I do not see "DNS is made easier"
as a compelling reason - this is setup once for the top level domain
or domains ("8 ip6.arpa zones for a /29"), and then the much more interesting
question on "how to deal with possibly zillions of records and subdomains?"
starts.
This said, I do not see much harm in this - the numbers permit doing /28s
as minimum size for LIRs.
OTOH, I do not see the need to state "/32 *or* /28" in the policy document,
because both the NCC and the LIRs will need to deal with non-nibble-sized
allocations forever - so forcing this now ("I need a /31, but have to
take a /28, why?") is not something I'd go for.
"allocation of /32 up to /28"
would do the job for those who want a /28 just fine.
(JFTR, we have a /32 that came from being a /35 - and it has never been
extended to a /29, because, why? We're never going to fill it, unless
our business model changes in very significantly).
Short answer: neutral on the /28 thing, but permit a range.
