For the journal you always keep all log history in it's original

On low-bandwidth systems, like laptops or diskless nodes, it's a
performance hit to generate the log entry in the first place. It's
really important to be able to configure the system to *generate* a
minimal amount of communications. Being able to filter the results
later is a separate issue.
That's a very good point: many systems do not fall into the
'infinite disk' desktop-like category. Case in point: embedded
systems like Beaglebone, Rasberry Pi, etc.: their entire disk is
2GB of flash storage. Logging is still useful for them but needs
to be very flexible and minimal.
There seems to be some common misconception that systemd is not
being in use by the embedded crowd or does not adhere to their needs
but the embedded system you are mentioning there are already using
systemd and journal along with few more and their journal (
journald.conf ) settings usually boil down to something like this
and serves their need...
[Journal]
Storage=none
SystemMaxUse=10M
MaxLevelStore=info
