I'm not sure that task needs a humanoid robot, but the ability to grab and manipulate all those packages and recover from failures is pretty good
An industrial robot arm with air powered suction cups would do the trick... https://bostondynamics.com/products/stretch/ ...
... So the task they work best at is the task there is already cheaper better robots specialized for.
Like LLMs being used to pick values out of JSON objects when jq would do the job 1000x more efficiently.
This is what this whole field feels like right now. Let's spend lots of time and energy to create a humanoid robot to do the things humans already decided humans were inefficient at and solved with specialised tools.
Like people saying "oh it can wash my dishes for me". Well, I haven't washed dishes in years, there's a thing called a dishwasher which does one thing and does it well.
"Oh it can do the vacuuming". We have robot vacuums which already do that.
