> There must a way to define how prefixes are assigned to always allow /48, if needed. If not in rfc6177-bis than in another RFC. We have already one limitation for SLAAC that makes sure every home gets at least one /64. We can add another one, in another RFC, to make sure /48 is given on a demand. That will insure future flexibility in any network and make the prefix assignment non-political process.

My understanding, no hats and potentially incorrect, is that any ISP I know of will respond to a DHCPv6 IA_PD with a prefix at least as large as requested, up to /48.
