Agreed. I'd just note that versioning also has to cope with the case 
where an add-on package A also provides an interface that further 
packages {B, C, ...} may use, so there is also a requirement for 
handling multiple installed versions of A, and for {B, C, ...} to be 
able to get the version that they need.

Unfortunately, I have no idea at this point how to solve such a problem!
