Be aware that so far there is no conflict checking or anything like that.

I think this is fine, @SoapDog. We agreed to have the core plugins hardcoded for all clients in milestone v0. IMHO It's just a question whether we want Adoptees to get warnings or errors if they double-require() stuff. Personally I'd prefer an error. It will be much simpler to reason about and not give false impressions about supporting multiple versions of plugins.
