Hopefully at some point in the future apartments/houses just come with privileged access entryways that you can manage, and delegate time-gated access to delivery services. That way the delivery person can just let themselves into your "airlock", put the package there, and leave without getting undue access to your private home and without it being a public space (like a porch) that requires a social contract to not be broken in order to remain secure.

Today's too early though, since IoT (eg. a connected doorlock) seems untrustworthy. What are some solutions that could be used to approximate it, I wonder?
