Which is the case for "deployments" that are *not servers* in the first
place. Many distros are oriented towards personal computers, which are
usually behind a firewall so junk traffic is not a concern, but which you
might want to SSH/VNC/RDP at unexpected moments.

For example, when I first started using systemd in ~2011, my laptop still
had a 5400 rpm HDD, and its boot time mattered far more than it does for
"deployments", so systemd's promise of on-demand startup of everything (to
reduce the boot I/O contention while still keeping the actual service
available) was particularly attractive.

(Of course, these days most systems have SSDs while even the baseline
systemd startup process runs twice as many Assorted Things as my full
desktop environment did in the past, so maybe the issue is no longer
relevant.)
