I am merely replying to what Kevin said. Using Kevin's list systemd
has in reality no advantage.

Of course you can add items to that list, such as the ones you
mentioned. I care nothing about those items you mentioned, while I
care about speed. Different people have different opinions, but having
an *official* list of advantages/disadvantages can only help.
specially if/when shit hits the fan, and tons of users experience
fundamental problems with systemd (which is a real possibility); they
will this is an imposition without a good reason.
