I agree. It really shouldn't but I find the thought that I do some 
things just for fun comforting. Nobody could claim that this wasn't 
according what was planned for the next sprint :-)

Buckminster has a qualifier generator that finds the latest commit that 
affects a given subtree (in this case a project). We use the timestamp 
of such commits directly for plug-in qualifiers. For features, we 
calculate the last timestamp for all included features, plug-ins, and 
the feature project itself and use that. There are some corner cases 
when this approach isn't fail proof but the way we use it, it works 
perfectly. Our qualifiers will remain the same as long as our code is 
unchanged.
