Bad Idea or not, stopgap or not, it was and remains technically, programmatically, and politically feasible.

The critical failure is that starting RIGHT NOW would deliver five years-ish too late, which renders it a moot point.  
In two or three years we may well regret not having done it in 2005; in seven years we will have had to have solved and 
deployed IPv6 successfully anyways.

We could have started it at a more opportune time in the past.  We could also have done other things like a straight 
IPv4-48 or IPv4-64, without the other protocol suite foo that's delayed IPv6 rollout.  Operators could have either used 
larger baseball bats or more participating numbers to make some IPv6 protocol design go the other way.  IETF could have 
realized they were in Epic Fail by Too Clever territory.

All of these things are water under the bridge now.  We have what we have.  It being amusing to grouse about mistakes 
of the past does not magically change the present.  We have rapidly vanishing IPv4 and no 240/4, IPv6, and no time.  
That is reality.

Pining for 240/4 fjords is not a time machine to change the past.
