I know of at least one pro brewer who uses chico yeast for fermenting a German hybrid. But I think the example you've given is the exception, not the rule, which is, I suppose, what you meant by "clean" in your title.
It's still an astute observation, though. I think even I remember something on the session about a brewery using 1056 for lagers.
But, in my opinion, the best part about home brewing is being able to switch up your yeast. I would go crazy if I were in a professional setting, and I couldn't play with new yeast strains for fear of contaminating a 15+ barrel batch.
