> See https://github.com/apache/arrow/pull/10992#issuecomment-910598194. Scanner would preserve the schema metadata but ExecPlan does not, and that makes sense in the general case. But this may result in unexpected behavior in R where we keep R attributes in the schema metadata. 
> We could probably determine in ExecPlan$Build which fields in the resulting Table are just carried forward from the underlying Dataset and pull in metadata for them to the result.
