I'm still kinda confused. What else would it do? I was under the impression (and I think others are as well) that all the `berks` commands run off a `Berksfile`. I don't really know how to clarify the language any more...

By the same token, the show, list, outdated, updated, and install commands would need to update their descriptions as well, because it's also unclear what they could do. Does #update update the cookbooks in my berksfile or the cookbooks in my local cookbook store? 

I don't see a value in any task that doesn't operate off a berksfile - it's not specific to your project and could give you faulty information. As such, I don't see the value in specifically adding all these clarifications to the descriptions.
