There was a huge discussion a while back on what this all should look
like, with Pekka and Paul and others. This here seems to fall quite a bit
short on that.

Also please cc all the people involved in that previous discussion.

Wrt the patches: Documentation seems to be awol at least, that definitely
needs to be fixed. Maybe fix that, resend, and then use that to move the
overall discussion forward with everyone?
