General question: why is it so common to use loopback, vs unix domain sockets? I haven't seen the latter used outside of mail infrastructure, and they seem slightly more secure to me regarding who can connect to them.

Two reasons we don't use unix domain sockets are: 1) they are not cross platform 2) they can't be created by browser extensions
