Code review comment for lp://staging/~yann-papouin/ocb-addons/6.1-bug-1234678-return-product-backorder-false

I agree with you, backorder_id should be False by design when duplicating a picking but fixing it in ocb-addons is something "too deep" as it may require more changes in other places (built-in addons and other ones) to reintroduce the backorder_id value. (note that this sentence is just an assertion, I didn't made any code search on this behavior).
