You are right. However the document origination source is required for
a useful version vector, because you can then track which peer has how
much of a source's writes. Which is useful if the source disappears.
You can then build a distributed picture of the eventual consistency
status.
Yes.
I guess it's a tradeoff between wanting a distributed overview and
wanting global anonymity. Maybe that's a valid configuration option,
rather than being policy.
Unless a node makes it's identity available in some way other than
replication, the source is still anonymous because there's no mapping
of node id to source URL (which might change in any case). To identify
the node you'd have to find the node, try to replicate from it, and
get lucky that the id it provides is the one you're looking for.
