Since no one complained, I guess nobody is against that solution. On
the other hand nobody seems to be excited by it, and actually, neither
do I. I mean, currently we have an intuitive mechanism to include
modules, but some weird link error messages if someone forgot to
include the right module.  And the we would change for more intuitive
error messages but with an unintuitive inclusion mechanism. So
eventually that's probably not worth it. In both cases we have to
compensate some unintuitiveness  by big warning in the documentation.
So let's keep the current state, and improve the doc. isn't it ?
