Now I am wondering if one could not just use SHACL or ShEX to describe
the binary Avro data directly? 

Salad is really only using Avro as a schema language, but SHACL and ShEX
are that too… 

Could one use that instead of the json? 
If so it would require some retooling (how much?), but it would have 
the advantage of making the mapping of the binary data to RDF clear and 
to keep that mapping very close to the data (since Avro data cannot be
understood without the schema).
