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
MaxLevelSyslog=info
