+Subject: [PATCH 1/3] extensionSystem: Get rid of _enabled boolean optimization
+
+At the moment a session mode either allows extensions or it doesn't.
+If it allows extensions, then the entire available list of
+configured extensions get enabled as soon as the session mode is
+entered.
+
+Since enabling or disabling extensions is an all or nothing situation,
+the code tracks whether extensions are already enabled when entering
+the session mode, and if so, avoids iterating through the extension list
+needlessly. It does this using a boolean named _enabled.
+
+In the future, the extensions themselves will be given some say on
+whether or not they should be enabled in a given session mode. This
+means, the configured extension list may contain extensions that
+shouldn't be enabled for a given session mode, and the _enabled boolean
+will no longer be appropriated.
+
+This commit drops the _enabled boolean optimization.

+Subject: [PATCH 2/3] extensionSystem: Allow extensions to run on the login
+ screen
+
+At the moment it's not realy possible to extend the login screen to do
+things it doesn't have built-in support for. This means in order
+to support niche use cases, those cases have to change the main
+code base. For instance, oVirt and Vmware deployments want to be able
+to automaticaly log in guest VMs when a user pre-authenticates through a
+console on a management host. To support those use cases, we added
+code to the login screen directly, even though most machines will never
+be associated with oVirt or Vmware management hosts.
+
+We also get requests from e.g. government users that need certain features
+at the login screen that wouldn't get used much outside of government
+deployments. For instance, we've gotten requests that a machine contains
+prominently displays that it has "Top Secret" information.
+
+All of these use cases seem like they would better handled via
+extensions that could be installed in the specific deployments. The
+problem is extensions only run in the user session, and get
+disabled at the login screen automatically.
+
+This commit changes that. Now extensions can specify in their metadata
+via a new sessionModes property, which modes that want to run in. For
+backward compatibility, if an extension doesn't specify which session
+modes it works in, its assumed the extension only works in the user
+session.
