The BSDs have far less lock-in with the default components than Linux distributions usually do. For example, I dislike the default syslog daemon, so, I disabled the default, and used my own. This involved adding two lines to /etc/rc.conf --

    syslog_ng_enable="YES"
    syslogd_enable="NO"

and that was it. Unlike systemd's way of doing it, the default syslog facility isn't started at all, doesn't run, period. Pretty much all the other low level services -- crond, dhcpd, ntpd, etc -- are the same way. This is one of the many failings as to how systemd operates. One should have reasonable defaults, but at the same time, if the defaults don't work, it should be easy to change them.

Well, journald is pretty much the one component of systemd that is very difficult to replace, but even so you can easily forward to another syslog daemon of your choice.

As for the rest, it's very much the same as with the BSD's, they all support their own versions of low level components and only them, and these can be changed by the user with compatible tools of their choice.

Forwarding to another process still means that if Journald goes belly up, the logging just died...
