Column pruning doesn't work for EXPLAIN ANALYZE

[martint]

EXPLAIN SELECT orderkey FROM orders

 Fragment 0 [SINGLE]
     Output layout: [orderkey]
     Output partitioning: SINGLE []
     Stage Execution Strategy: UNGROUPED_EXECUTION
     Output[orderkey]
     │   Layout: [orderkey:bigint]
     │   Estimates: {rows: 15000 (131.84kB), cpu: 131.84k, memory: 0B, network: 131.84kB}

            Layout: [orderkey:bigint]

 Fragment 1 [tpch:orders:15000]
     Output layout: [orderkey]
     Output partitioning: SINGLE []
     Stage Execution Strategy: UNGROUPED_EXECUTION
     TableScan[tpch:orders:sf0.01, grouped = false]

         Estimates: {rows: 15000 (131.84kB), cpu: 131.84k, memory: 0B, network: 0B}
         orderkey := tpch:orderkey
         tpch:orderstatus
             :: [[F], [O], [P]]

But:

EXPLAIN ANALYZE SELECT orderkey FROM orders

Ignores the fact that only orderkey is being selected and produces:
