More options to lock block schedules

I would like to see variety in how block schedules are locked. I know there is the “Strict Block” lock which prevents you from turning off the block schedule when an ongoing active hour on the schedule is active, but I would also like to see other locking options such as a variable random text generator, a timer that locks the block schedule until a set amount of time or a specific time and date has arrived, a countdown that forces user to wait a set amount of minutes or hours before the block schedule is unlocked.
