By that logic, wouldn't IPv4 also be considered a loser because everyone
has been carrying the overhead of bloated packets for years?  Especially
near the beginning, we didn't need a 32-bit-sized address ...

And why would we jump to 64-bit addressing, since you're so worried about
the bloat in packets?  Wouldn't it be more sensible to move to 36-bit or
40-bit addresses?  If we jump to 64, aren't we wasting at least 56 bits 
per packet then (2 * (64 - 36))?

And if we're going to completely re-work IP, why wouldn't we just move to
a version that ensures addresses are plentiful?  And if we're going to do
that, why not just go with 128 bits?

Bits are cheap.  I mean, really, really, really, REALLY cheap.  Trading
a few bytes worth in order to get a solution that'll last us for the rest
of our lifetimes (and then some) is a no-brainer.

However, if you're really interested in it, I suggest you read the message
I posted, subject of "Important", a few days ago.  It suggests a
bloat-free way to continue to grow the existing network.  It's completely
practical and I think you should promote it.
