Review comment:
This assumes that the incoming Avro schema has field IDs. The only reason to
copy in other places is when we are building a replacement schema for some
reason, like if the map didn't have the LogicalMap annotation (some old
manifest files), or if the value schema is a subset because only some of its
fields were projected.
