Your definition of core modules is going to differ from mine, and the
next persons, and the next.

It's not simple.  It's not easy.  It buys you very very little and it
leaves the maintainers having to continuously guess which package a
module goes into.  Then there's the requests to move them from one to
the other.

I'm _very_ against splitting the modules up more than they already are.
The modules-extra subpackage has been somewhat a pain already, and those
are the modules that are very rarely used.  Extending it to common ones
leaves me with a headache just thinking about it.
