Soil Bag Gardening?

Someone on Facebook posted a link to an article on "soil bag gardening". It looks like something I'd like to do this year. The ground where the vegetable/herb garden will be has been compacted by horse hooves for the last few years. Even if I till it, I'd still have to amend it. For this idea, you take a bag of topsoil, poke holes in the bottom for drainage, place it where you want it, slice open the top and plant your seeds or seedlings. Easy peasy. In the fall, remove the plastic and there you go. You can also do something similar with straw.
