Sure, they do different things. Nonetheless, there is repetition that could be reduced. In fact there's potentially a fourth place now where we reference dependency information again: 4. Use this version of this component (though this may be maintained outside of the actual package) In at least 3 places we express dependency information. For different *purposes* in each case, but we still state something like: 1. "we use dependency X, and please download and install it" 2. "we use dependency X, please configure it" 3. "we use dependency X, please import the following from it" It'd be nice if I only had to say "I want to import from dependency X, please make sure it's there and available." Actually this is a little bit like zc.resourcelibrary can make resources appear on your page headers when you write code that needs it. Of course this is sometimes not possible, as there's not enough information available, or there are multiple separate ways to configure it. But there is significant repetition spread out across the codebase. It's not in one place, which forces a repetition in referring to the component being installed/configured/imported. My response is to think about ways to reduce this (while of course, looking for ways to retain power and flexibility).
