This.

Not just user-specific settings, but session-specific settings.

Doesn't seem to, and I don't see why it would. According to the README:

    The AccountsService project provides

     - A set of D-Bus interfaces for querying and manipulating user
     account information.

     - An implementation of these interfaces based on the usermod(8),
     useradd(8) and userdel(8) commands.

There's nothing session-specific about that.
