CSP isn't only useful for stopping XS either.  It can be a policy enforcement for where scripts can come from.  Just like it can control framing, which isn't really about XSS either.   I think it would be a lot less useful if it didn't include those capabilities/functions, as those are some of my major initial use cases.
