This is a reasonable place to do a risk analysis, how difficult is it to run the tool that can handle the file format of journald on a system that may not be working 100%, how often are the local logs not going to be sent via syslog to a central location? I don't think the designers of this would have done it this way unless they were convinced this was still a win but it's a discussion that can be had.

rsyslog can get the logs from journald very rapidly, pretty close to real-time.

the designers of journald didn't have any idea what rsyslog, syslog-ng and similar logging daemons were able to do at the time they started journald, their justification of journald is full of "syslog can't do this" arguments that were true of traditional syslog, but not true on any of the modern syslog daemons.

journald works pretty well for a single machine personal system, but it was built in ignorance of how logging works in larger environments.

Maybe you are right but it seems that when the systemd developers do something they do a ton of research before hand before committing resources. In any event it is pretty plain and stated that the journal isn't even trying to deal with networked logging or larger environments, it's main use case is the single personal machine, and capturing logs from early-boot which are normally lost. You don't judge a fish by how well it can climb trees.
