This is largely a solved problem. Have your mail held (admittedly you can only do this for up to 30 days in the US). And just don't order anything else that will potentially arrive while you're away.

At least some of the major package carriers in the US offer package-holds.

Assuming that putting a hold on the layer of abstraction is no harder than putting a hold on your mail, what you're describing is harder than it would be with the abstraction layer. It's also less effective, as it doesn't handle packages sent by other people, unexpected delays in shipping, or unplanned trips.

So is a friend or neighbour who stops by once a day to feed the plants, water the cats, and empty the mailbox.
