I'm spoiled- I braid almost all of my onions. I usually have about a bagful of some whose tops broke off too short to braid, but I love the convenience of the braids.
You can pick out any size onion from the braid and snip it off. If one starts to go bad and rot, it doesn't contaminate a dozen which are pressed up against it. And again, you just snip it and toss it. Nothing I hate worse than digging through a bag of onions for the "right one" and encountering a slimy one! Yuck!
I recycle baling twine from the barn to reinforce the braids, and hang them by a loop tied in the twine. Once you've done it a bit, you can braid 100# of onions in an hour or so. Anyone who needs much more than that for a year probably has their own methods anyway!
These make great gifts, BTW, as do garlic braids. My daughter always had one hanging in her apartment kitchen when she was at college, and her friends all were crazy about how "pretty" it was. I just thought it was practical.
But that's a neat idea about the scrubbies. I'll have to look at one- theres a few hanging around here somewhere
