// - this is a demo mode session: Same as guest session.

//
// Furthermore there are some situations that we don't need to special case,
// although the ownership question might seem tricky:
// - this is a managed guest session: To start a MGS, devices need
// to first go through enterprise enrollment, which is an action that
// already establishes device ownership.
// - this is a kiosk session: Currently kiosk sessions are only allowed after
// enterprise enrollment, which similar to MGS, establishes device
// ownership.
//
// This must be called after login.
