Romain Manni-Bucau commented on CDI-114:

If you know the type you can surely sort it out with producers but producers generally means 'do it yourself' which would lead to keeping the component manager more or less. However an extension can produce any bean based on a qualifier (see https://gist.github.com/antoinesd/3097661ca99fa61900fb but instead of Object you can use the xwiki-api/interfaces). Issue allowing runtime registration is you would need to reboot the container more or less bypassing the scanning only to validate injection points and to reinject all created beans to ensure the consistency. It is a lot of work and overhead at runtime for not that much gain since a manager is easy and fast for this kind of dynamic registration - even with subclassloaders. Hope this makes some sense
