I don't think there is a contradiction between resource->resource and
representation specific *filtering* of links. A resource can have MANY links
but does not have to include all of them with every representation. But it
is important that links are bound to the resource itself and not to a
specific representation.

I fully agree and if such consistency is required for an application to work
properly, it must be made a requirement by that application.
