   The examples on that issue were compression codec, which is stored in the Avro and Parquet formats (and I assume ORC) and CSV delimiter. I don't think either of those is a compelling reason to add custom metadata.
   
   This adds the idea of a path "namespaced" differently in multiple contexts. I don't get that. What do you mean?
