desired_links should work as a logical AND by default in order to be more valuable for network use cases and only filter on status.UP links. undesired_links can still work as a logical OR though.
I've had the chance to discuss some cases today with @jab1982 and @italovalcy. A logical AND for desired_links allow network operators to further specify which links should be present in a path, and this can be strategic when trying to further target a path as a constraint.
