Simon,
As I see it the main difference regarding sail area is how the masts surface area is calculated.
Current rule:
Mast area = mainsail luff length multiplied by the circumference of the mast.
Proposed rule:
Mast area = mast length *maximum circumference of the mast * 0.5
Mast length is longer than max luff length, which means that the area of the mast under the lower measurement mark now is included in total mainsail area?
