Letting people in without giving them a key (or if they forgot their key) is the use case. Also if you have smart home stuff like home assistant, you can program it to lock on its own based on conditions (like night time or your phone leaves the house).
Re the first part: nobody enters my house if they don’t have a key and I’m not present. Re the second part, I don’t trust any software-based technology near enough to rely on that kind of stuff without double-checking. . Turn the key, done.
