They probably picked the 9 amp because it was a value they used in several other accessory applications over the years and maybe the holder and fuse was a standard SFE size item at a lot of dealers. SFE 7.5 used the same size holder and more than adequate for the needs so surprising they did go so high. I would not go lower than 7 because the backup lights on PB cars are also protected by that fuse.
