I think the reason this is more damaging to developers because as a developer you probably can't produce anything without focusing. As to communicating when you don't want to be interrupted -- I am still working from home, and even my kids know that when the door to the office is closed they can't interrupt. When I was still working at the office I was telling people that headphones == do not disturb. Obviously, you need to provide them some way to send you the message. I try to keep my office doors open and headphones off when not necessary. I also tell people shoot an email and I will respond when I can.
