If you're concerned about storage wear you'd just run journald without /var/log/journal so it's volatile (tmpfs) only. At least that way you still have journals for your current boot and functionality like `systemctl status $service` can still tell you some journal information.

Yeah this is a lot of work to avoid reading journald.conf, switching the storage to volatile, and capping the memory usage to whatever you want.
