Yes, but communication helps - so long as you actually deliver. It's one thing to talk out your ass and another to deliver on it. If you deliver or are in the process of doing so, it certainly helps to assuage a lot of confusion and angst by giving a simple 'Hey, here's what we're working on.' So long as people know that the devs know it goes a long way. No feedback at all is definitely the wrong way to go. Even if they just said, 'No we're not ever going to anymore HL.' it would be better than wondering for years.
