Does it? If you mean 'all things under the systemd umbrella' then sure, but if you think in terms of systemd (core), systemd-networkd, systemd-homed, etc. isn't it pretty much as 'one thing'(s) as it could reasonably be?
And the umbrella just seems arbitrary - GNU, Mozilla, X11, anything that's a package group, etc. are also failing.
You're right, systemd does fail in this.
