If you want to experiment with a yeoman generator in ways that are very different from the established patterns here than maybe you should consider a separate yeoman plug-in (possibly forked from this code).

On top of that . . . if it is something that doesn't use the generator option, then why are you using yeoman in the first place? The same thing could be accomplished with through other means (like doing more in the bath file).
