Don't contenders use a block floating on the bridle?
I think there is a balance between allowing independent control of sheeting in and leach tension, vs wanting to control both together?
As you ease the sheet in a gust, you want to allow a little more twist?

Probably floating would be best, very rarely does a mono rig need sheeting to the centreline. Centre lining the boom may possibly give the feel of pointing high but is usually slower and perhaps even result in a lower course because even though the boat is pointing high the foils are moving so slowly they are stalled and making lots of leeway.   

I think this is what happens. I fixed a pulley block centrally on spectra line tied off to the ends of the rack tracks. When I saw the Punk I was going to try and fashion something along the lines of that but in the end a nasty clew first stack and  the nose of the boat somehow getting between the boom end sheet and the stern convinced me after a nightmare trying to sort it all out in the water, to go back to centre sheeting.

It works a bit differently on the Laser IMHO. 
Before the new kicker arrangement you would to some extent control mast bent with the main sheet (maybe this is an un-stayed rig thing).
Upwind is always block to block bending the mast as much as possible
(probably a bit different now there is sensible purchase on the kicker).

The Laser rig is also pretty unsophisticated and I don't think the same level of thought was put into it as the likes of the Zero, Aero, Blaze etc etc (modern boats).

Also being a strict One Design, not much changes quickly (eg the sail)

The Laser is a bit different.  Before the new kicker came in the sheeting angle couldn't be adjusted, if the bridle was eased the angle reduced but then it was too narrow, so the bridle was always tight.  Since the new kicker it's been possible to tighten the kicker and ease the main, increasing the sheeting angle whilst still keeping a flat sail and this has allowed more efficient sailing in stronger winds.
