I think Haas is basically right, that the structure flows from the community structure, and that it's not clear alterations would be a net win. pgsql-hackers is producing the kind of docs only they can, but many usful kinds of docs they cannot produce (per Haas's theory, e.g. more narrative in nature) are delegated to the relative anarchy of the Internet, in blogs, comment threads, stack exchange, and such. While there should be a lot of hesitancy at the implied assumption that any particular arrangement is at the efficient frontier -- most situations can be improved in most or all dimensions -- an exchanged loss in the kind of documents that pgsql-hackers is suited to producing is hard to replace.
