Why is it ironic? I've been using systemd since before it was part of any distribution; it has been extremely convenient and helpful from the very start, and every year it gets even better (as new components mature enough to enable, e.g. systemd-timesyncd).
Ironically because the opinionated consistency Systemd's session + login management brought made Xrdp saner to operate, while changing traditional things like persistent process after log off (by default), and device-console/session attachment.
