WTH is up with doors

No complaint specifically, but something that’s been bothering me with various home automation solutions.
Now that we have areas (that many seem to use as substitute for rooms) I think it’s time to rethink how door/windows sensors (opening or locks) are presented.

I feel some cool things could be done in abstracting doors as an entry-point between areas, but I’m not entirely sure what for. I have ideas that are just out of reach and that I can’t formulate.

Anyone else think the whole concept of “openings” (door and/or windows) in home automation is missing its true potential?
Like “I’ve detected motion in a room that has all doors/windows closed, so until one is opened I must consider the room as occupied”?

I’m not even sure the idea really makes sense or is useful, but I think there’s something to explore…
