I think the original motivation for major versions of the form A.B was, 
at least for me, that preliminary versions can be indicated by A=0.

Personally, I don't consider 1.0 to be "done". Rather version "1.0" 
means that the core functionality has been implemented and that the 
package authors now have an idea what the core API should look like -- 
up to future changes. Thus, I think  containers  perfectly well deserves 
version 1.0.
