Those 3 stands in the North area by the old flying club have always been shown as commercial stand but were used by Ocean Sky and then Signature. Back in the day of the 2012 planning permission there were 48 commercial stands shown, now there are 46 proposed. Signature will loose 3 stands but gain 1 under this plan. Maybe gain 2, as I can't remember the status of stand 10 at the moment.
I was thinking Signature would gain out of this development but maybe they are being further squeezed.
