I would probably support something like that with a few caveats.  One
being that we try to keep things as aggregated as possible.  If someone
grows out of a /48, they get say, a /46 and don't get additional
discontiguous /48 nets.  Also, we should wait a while to do that. Once a
significant portion of traffic has moved to v6, people might want to
make decisions to mitigate routing table bloat with v4.  Once v6 traffic
exceeds v4 traffic, some of those decisions become easier to make
(accept v4 routes from peers and shove any other traffic out to transit
with a default, for example, rather than take full v4 routes from
multiple transit peers.).  I might be willing to accept some sub-optimal
routing for v4 once v6 exceeds v4.  Maybe others would be willing to, as
well.
