The lack of market incentives is, IMO, intimately connected to the lack of new
functionality - functionality which would have meant a more ambitious design.
IPv6 and Neighbor Discovery were designed so ambitiously that they
have so much new functionality.
The problem is that the added functionality does not function as
expected, is not required by the market and is rather harmful
than useless.
Examples are 16B addresses, unlimited optional headers, path MTU
discovery, support for NBMA (ATM) networks, stateless auto
configuration and flow.
So, how can you say "more ambitious"?
but spent most of its
technical energy thinking about a 'clean slate' design; in a
way, one could say it was too ambitious in the 'engineering
details', as it were.
Using a clean slate is of no help when you write much more than
what was already written on a scribbled slate.
