Not necessarily this system, but I've seen plenty of similar basket style breweries being used professionally. In Australia, for instance, I saw a big homebrew shop using a Speidiel version of this idea to produce wort kits. Rockpit brewing in Orlando, uses (or used - they were talking about upgrading hwen I saw them last in pre-COVID times) a very similar idea. It's not a bad way to go for a small footprint brewery. Lots of obvious limitations, but there you are.
