We recently added characteristics to Product Spec Relationship in the Product Catalog API TMF620, based on a specific use case.
If you can identify a specific use case for characteristics on Resource Relationships, feel free to add here (please show real/realistic business example with actual names of specs and characteristics), we can consider as a future enhancement for the Resource space.
