The part that is missing isn't the "some ISPs", it's "all ISPs". Also,
I don't know of any DNS service provider that offers a product to handle
delegations from the IN-ADDR.ARPA and IP6.ARPA trees.
I'm focusing on the SOHO customer market with my proposal.
The allocation of IPv6 space with prefixes shorter than /64 is indeed a
consideration for bigger administrative domains like country
governments, but on the other end, SOHO customers would be happy with
/96, /104 or even /112 allocations if they could get them. (Just how
many light bulbs, fridges, toasters, doorbells, phones, &c does SOHOs
have?) I would *not* like to see "us" make the same mistake with IPv6
that was made with IPv4, handing out large blocks of space like so many
pieces of M&M or Skittles candy.
