I like the idea of not always having to add a new root node type for each "section".

But in the current architecture, a section is defined precisely by a root node type (and, in a non-fundamental way, by a superdoc to display recent posts and a posting form).

I think, essentially, the change I'm proposing is radical enough that the developer(s) should probably work it out on a copy of the site. (which, as we know, is showstopper of a roadblock at present.)

I just wanted to capture my thoughts here. Anybody could work on this.

But you are the only one who was added to gods with a mandate to work on it (patch approval).

The "this" I was referring to was the subject of this thread. My point was that someone else — if a suitably motivated devil were found — could work on this while I pursue the subject of my mandate.
