no, as we believe contextual relationships/tuples are often a non-ideal solution. For data that does not change all that often, such as group membership, the relationships should be written into SpiceDB to ensure that proper caching can be done. For dynamic information, such as whether the user has a particular scope, we are working on the caveats feature https://github.com/authzed/spicedb/issues/386. Contextual tuples have a number of major problems, including causing caches to no longer work, issues with consistency, questions around data overlap, etc
