Yes. When the requirement chain that fails has 3 or more elements. 
'Required by' is the package that asked for the failed requirement. 'For 
installing' is the root package you are trying to install.

Sure, please check #requireUnlessIn:main:requiringFeature:, tweak it to 
suit your taste and repost. Thanks!

Yes... That would be nice to have. Maybe we can allow package names that 
have the feature name as a prefix, meaning that they match 
'FeatureName*'. This would still let us avoid scanning every .pck.st 
file just in case.

That's because of using #notify: Maybe we'd call #inform: instead.
