Have to remember too that carrying packages will require more thrust. Also, they would probably be large enough that big birds don’t try or fail to take them down. I was flying a ~35g drone around my yard last year and a hawk of some kind snatched it right out of the air and tried to kill it on top of a tree. Thankfully got it back with some diplomacy (yelling at bird) and no one was hurt. Drone still flies to this day…

Got it on camera too, the claws look massive.
