Privacy enhancing extensions such as this one block access to cross-domain subresources from sites known for pervasive user tracking. If some subresources avoid beforeload, they won't be blocked, and users will be tracked. I would expect that whatever an extension or a Web site wants to do with beforeload, it trusts that there is no bypass such as the Link header.
Obviously, nothing will change in practice until sites actually start using the Link header. But widespread use of Link is something we should plan for if we're going to support it.
