The beef isn't with systemd upstream which already has a very simple/boring workaround for this, it's with the debian package maintainer (some people here are wearing multiple hats).

Really the whole raison d'etre of debian is move at this pace to prioritize stability/compatibility. If you don't like that philosophy there are other distros but a package maintainer's primary job is to repackage software for that distro (which presumably users have chosen for a reason), not comply with upstream.
