Review Comment:
I understand not wanting to bother with `output`, but I think the best
practice is to preserve `output` from the logical plan to the physical plan.
That's because resolution has occurred with the IDs from the logical plan and
we don't want to reassign internal IDs in the physical plan. They should always
match. That's why most Spark plans (like `DescribeTableExec`) copy and reuse
the output attrs.
