Indeed, there is a big difference between "dropping support for version 
X" and "requiring version Y".

Do you realize how a (relatively) simple question again gets massively 
complicated by the fact that we try to establish a policy for all the 
 >150 Boost libraries ? I'm fully aware that the library 
interdependencies will have an effect on what version a given library 
ends up requiring, but that doesn't mean we have to impose version 
requirements on all libraries at once.

(I seem to have the doubtful honour of writing the 100th message in this 
thread. That itself should ring an alarm bell...)
