With all due respect unless you are/were a Southampton ATCO I would suggest that you are not qualified to make this statement.
I see that Luton has now been added to the discussion, little or no relevance to SOU. Their RWY 08 requires about a 200 metre backtrack, and 26 a 400 metre backtrack, with other taxiways to permit a landed aircraft to vacate. Nothing near the 1000 metre or so baktrack at SOU when the extension is completed.
