I think the concept of useless use of cat is one of the few things I strongly disagree with in software development. Most things have their trade-offs, pros and cons, but using cat to start a pipe makes everything composable and easy to work with, it's pretty much universally good. The moment you drop it because of the small redundancy, you have to make sure you don't mess up the params for whatever comes next, and that overhead is in my opinion never worth what you gain by dropping cat.
