I've decided that it's too much effort for me to keep all the existing add-ons up to date between versions, so I'm leaving that up to the creators for now. But I'll soon finish with the fine-tuning of the joint parameters and JCMs for the body (with the possible exception of hands and feet) and will then concentrate on the face. So I'll look through the existing morphs and ERC setups and take what I find useful (supposed I have permission) or let those things inspire me if for some reason I can't use them directly.

I'm not sure how much should be included directly in the CR2. I think the JCMs and expression morphs are universally useful, and if done well, it's not all that likely that we'll have many different versions. So those will be included. But I think most shaping morphs should probably be loaded separately. And if they are, I'd like to keep them in separate packages as well, because that would make it easier to publish updates.
