Nah, but I think that the addition of a locking "package box" may resurrect a concept similar to a milk door; a small niche in the wall near the front door that can be opened with a code, and also opened from the inside. My MIL's house has a milk door.
I really don't think that the delivery services would love the idea of deliveries commonly going to the back of single-occupancy homes; that would take longer for each delivery, slowing the route time.
BTW, there are all sorts of package dropboxes available for sale right now. Some are disguised as things like planters and gateposts, others are utilitarian steel. With some, you just leave an open padlock on the hasp, and the delivery person is supposed to close it after delivery, some have combination locks where you can supply a code, and others have UPS-like chamber doors or heavy rubber flanges that allow things to go in from the top without a key, but cannot be reached into to pull anything out. I would think that after the pandemic, new homes being built will probably offer having them built-in as an option, but you can certainly add a free-standing one any time you like. Just Google "package dropbox shipping" and you'll see hundreds of choices.
