Sorry, just now I get what you're talking about here ;-)
Log rotation is done by journald and the limits are checked before
each append. All other applications writing to /var/log/journal should
do the same. I guess that rules out 1) and 2).
Mounting the server /var/log/journal on the clients and configuring
the clients to use the same limits as the server seems ok, as all
writers can see the whole data and do the rotation themselves.
