Similarly whether messages should be coming from the channel’s JID or the user’s proxy JID. I think the argument that things should come from the user’s in-channel JID rather than the channel’s is reasonable - this is also what happens already in MUC and is familiar.

Why was that again? Do we really need to encode four bits of information
in a single JID?
Otherwise we could go with channel at service/user and, possibly
optionally, put the (pseudo) resource as metadata into an extension
element. And if a client really wants to enumerate all resources/clients
of a remote MIX user, he could look at the presence node of the user.
That is essentially jonas's proposal:
from="4973d5d365f8 at mixservice.domain.example/client-resource"
to="user at other.example">
with the channel, resource and user swapped. So you end up with:
<message from="channel at mixservice.domain.example/user"
to="user at other.example" …>
