The thing is, he's not entirely wrong: su *is*, really, a
broken concept.
What he conveniently forgets, of course, is that having a
real root session with a separated environment, which is
what the new feature does, could already be achieved... by
logging in as root.

Duh!

So, this is just yet another propaganda stunt.
"su sucks. See? UNIX sucks! And now systemd can do so much
better than UNIX: it gives you real root sessions that do not
leak anything from the user environment."
"But, um, can't UNIX already do that ?..."
"NO NO NO systemd does it better because <insert confusing
buzzwords that will bamboozle executives and journalists>"

It's been like this since day 1 of systemd, and I'm not
expecting it to change any time soon.
