How does this differ from IsSessionStarted and IsUserLoggedIn? Does it makes
sense to have a single property that returns an enum?

It's different in a sense that it's not a state (like UserLoggedIn and
SessionStarted). OTOH, it's value is equivalent to IsSessionStarted(). So it
actually makes sense to revert it at all and use IsSessionStarted directly.
