Your justification is incoherent. If you want to administer "old school" Linux, you just use the old commands. If you want to administer a dist with systemd you use the new commands, or the old commands which are symlinked into their new equivalents.
I'm not sure what the fuck "old-school" even means since it has constantly changed from its inception. Except by saying "old-school" you demonstrate that Amish mentality - drawing a line in the sand and saying things shouldn't possibly progress beyond that point, even if its for the better.
All the whining over systemd could apply equally to procfs, devfs, pci, usb, btrfs, acls, etc. A barrage of changes that (competent) admins are expected to incorporate into their knowledge.
