Grep and tail are fine for users (or for advanced users.) They are less fine for automated log parsing.
I'm a bit worried, though, about how divergent the platforms for server and desktop Linux might end up becoming by going down the path of Journal vs. Syslog - server admins don't always have the same needs as desktop users, but it can't be helpful if the tools they use diverge too much.
A few configuration parameters from journald.conf may be overridden on the kernel command line:
systemd.journald.forward_to_syslog=, systemd.journald.forward_to_kmsg=, systemd.journald.forward_to_console=
Enables/disables forwarding of collected log messages to syslog, the kernel log buffer or the system console.
