Runtime upgrade in parachain is stored in all PoV before being applied

[crystalin]

When performing a runtime upgrade on parachain, the storage_proof seems to include the code the runtime in all the blocks before the parachainSystem.ValidationFunctionApplied is executed.
This is from a local node (no extrinsic except the runtime upgrade)
