Excellent idea. More than that, I suggest that we should have a living
specification for sessions in general. For each of
{start up, log in with password, log in automatically, lock screen
manually, lock screen automatically, unlock, switch user account,
log out, suspend, hibernate, restart, shut down},
we should define how that function is made available (or not), looks,
behaves, and fails gracefully, for
{a standard user account, an admin account, a guest session, a
live/test-drive session}.
That way we can ensure everything is consistent, and we can comprehend
the whole scope when we make functional changes. (For example, if in
future we added a "Restart Into Windows" function for dual-booting,
specifying it for all those cases would make both the design and the
implementation more robust.)
