Hi, I had a look at the latest v02 patches.

Hm. I don't think a proto_version check is required for "origin".

IIUC, the protocol version number indicates the message byte format.
It's needed so that those messages bytes can be read/written in the
same/compatible way. OTOH I thought the "origin" option has nothing
really to do with actual message formats on the wire; I think it works
just by filtering up-front to decide either to send the changes or not
send the changes. For example, so long as PostgreSQL >= v16, I expect
you could probably use "origin" with any proto_version you wanted.

I won't keep pushing to rearrange the docs. I think all the content is
OK anyway, so let's see if other people have any opinions on how the
new information is best presented.
