Here's the release notes for 205:

        * logind has been updated to make use of scope and slice units
          for managing user sessions. As a user logs in he will get
          his own private slice unit, to which all sessions are added
          as scope units. We also added support for automatically
          adding an instance of user@.service for the user into the
          slice. Effectively logind will no longer create cgroup
          hierarchies on its own now, it will defer entirely to PID 1
          for this by means of scope, service and slice units. Since
          user sessions this way become entities managed by PID 1
          the output of "systemctl" is now a lot more comprehensive.

That's why. Logind used to have more scope than it used to, now it
defers some of its functionality to other programs so that it could do
it's "one thing well". That's the very definition of "not monolithic".

Why can't you make it work separately after 205? Because 205 is
a MAJOR VERSION BUMP on an actively developed program.
Nobody's yet written a program that fills the functionality that logind
depends on. Better evidence is that it could work outside of systemd
in the first place. You don't expect public APIs to remain stable
past major version bumps.

So there, once again a long, long pompous rant of acting like a
know-it-all about stuff you've never bothered reading.
