WTH can't I lock an entity

Some Entities may benefit from being lockable.
E.g. when going onto my terrace, I may want to lock my blinds. Otherwise, if they lower, I cannot go back in.

My wish is, that HA supports the generic functionality to lock entities/devices.
A small lock would be displayed next to the (e.g.) switch and when toggeling the switch, it would not switch the entity.

Thanks in advance, Santa! :slight_smile:

This sounds like an input_boolean helper to me.
