Send + Sync is maybe not enough but wouldn't it be possible to say: as long as the memory location is read-only you can parallelize access to it. Send + Sync helps pass the read-only data through without synchronization to all threads, while the rest of the Send and exclusive mutability system flags the tricky points for you. I can see that Send/Sync by itself does not tell you if the data is read only or just internally synchronizing mutation.
