Review Comment:
   After implementing it, while it's doable it does seem to complicate more. 
I'll see about simplifying it, but we may just want to go back to surfacing 
schema IDs at the data model level or even serializing the entire schema to 
keep parsing really simple. For just using schema ID, then engines can select 
their representation and then do view.schema(repr.schemaId())
