This is great. Not having the attack surface of sudo (and not even being a SUID binary) certainly are great additions.
And I hope people realize that systemd is not one large thing, but a (large) collection of tools.
XZ-utils rings a bell ? It was among others Debian wanting to pull in part of a systemd tool into openssh and that almost turned into a world wide disaster :(
Thanks for that write up. Made my day! ๐
