Not entirely; 'man NetworkManager' has more details, but you will get
up/down events when *any* NM managed interface is taken up or down, not
just when there's a connection or not.  If you get a "down" event, there
may well be another interface that still has a connection.

We could explore the possibility of adding two more events indicating
when there is any connection, and when there is no longer any
connection.

There are "system" connections and "user" connections.  Since you're
only dealing with root, all your connections should probably be "system"
connections.  System connections are stored either by distro-specific
plugins, or by the distro-agnostic 'keyfile' plugin to
NetworkManager/nm-system-settings.
See /etc/NetworkManager/nm-system-settings.conf for more information, or
take a look at:
