That's overstating the case. As I understand it the address is resolved by a pathname lookup like any other--it can follow symlinks, is relative to the current working directory and filesystem namespace, etc. So a unix-domain socket equivalent to openat() would at least be well-defined--whether it's needed or not, I don't know.
