(I'll still call 'core env' 'bean env' to be more clear, but I agree 
with you in the end)

Ok, I see now. The fact is simply that cocoon cannot work without an 
environment. So the "core" without an environment is useless, but it's 
still the core... it all boils down to what "core" means.

/If/ I take the servlet environment and the cli one out of the core, the 
core does not work. This means that the "working core" would be 
core+1environment impl, where the env. impl. is any of the 
./src/environments/**

Stepping back a moment, would we want a core that is not self 
sustaining? I think no. So the default environment kept in core would be 
the bean one. But there needs to be a bean one, without an env. impl. 
Cocoon doesn't work.

Finally, since it's in the core, it would be the 'core' environment.

I see it in o.a.c.environments.impl.core, that's why I said it.
