My understanding at the time from talking to numerous people was that those who knew how knew that handling variable length addresses was not really a problem and I have heard since that that many people who were concerned about that have said they were mistaken at the time.
Actually since addresses belong to layers rather than protocols, the point is moot. One can have your cake and eat it too.
The real crime with not adopting CLNP was passing up a chance to reduce router table size by a factor of probably between 3 or 4. That would be real handy right about now.
Now *that* was truly irresponsible, if not criminal. We could be reducing the number of v4 routes to increase the number of v6 routes instead of the other way around. But then v6 was unnecessary to begin with, so was CLNP.
