[xwiki-users] Components best practices

Hi, I wonder if they are some specific recommendations, in addition to what's described in [1] and [2] ? My particular use-case, is to know if there is such a rule as to create one maven module for one xwiki component, or if several components can be grouped in the same maven module. Detailed description: for the xwiki-contrib-mailarchive-api, I started from a monolithic class (@Component), then I started splitting it up in several classes. While each of these sub-groups could be considered components (highly related to the mail archive use-case, ie not particularly re-usable), for now their life-cycle is managed by the main Component (ie if one of them needs a query manager, it is not injected by xwiki framework, but provided to it by the main Component). Would it be recommended to move to a whole component architecture, and make all these sub-components Components managed by xwiki framework ? Are there any limitations (perfs...) to do it that way ? I'm pretty sure it's obvious to xwiki devs, but I prefer to ask.
