>> "If we want the RDF to be an equal sibling to xml and JSON then round tripping needs to be signature safe." David.. Lloyd's comment points out the need for a significant and non-trivial "uptick" in the level of care that will have to be taken when generating RDF. I certainly haven't been to every single FHIR RDF meeting (so please correct me if I'm wrong), but I don't recall "signature safety" being discussed much (if at all) when we've discussed aspects of round tripping.
It has been mentioned before, as a way to clarify what qualifies as successful round tripping. Successful round tripping means getting back "the same thing" if you convert from one FHIR serialization to another and back again. But in deciding what we mean by "the same thing" one might not expect something like whitespace differences to count as consequential differences, whereas other changes definitely should be considered important. The digital signature criteria provide a way to arbitrate between important and unimportant differences.
