There's an even bigger one: server connections can only send stanzas in one
direction. Although that's more of a protocol thing than a schema thing, if
you want to get picky. :)

I always figured components were more like clients than servers. Clients and
components make single outbound connections, and construct and parse stanzas
for server routing. In contrast, servers do very little stanza manipulation
(and, depending on how your server is designed, even the roster stuff might
be in a component). It is stanza manipulation that really kicks your ass
when it comes to the different namespaces, and so sharing the same one as
clients would be useful I think.
