Well there are a couple of reasons:
1. The first valve in the stack always goes to the rear remotes and it is cheaper to plumb from the back side for that valve. Plus the guys on the assembly line didn't have to cope with the tin shroud.
2. The first valve is different from the other two. It only has two service ports. The opposite side single port is used for the PS U-tube.
3. The back side of the two outside valves are covered with the lever bracket for all three valves.
4. The manifolds for the outer two valves need to exit to the front to simplify the mid-tractor hydraulic outlet position. Those four steel hydraulic lines take up alot of space. Why complicate all that spaghetti with two more ports?
There are probably a few more reasons but those come to mind. Just pull back the shroud and have at it. It shouldn't shorten the remaining time you have left on this earth.
