I like the footbox on mine, and i had the impression that depending on how the bird is hung it does make a difference in the lay.

But design-wise afaik it is there to give you an unrestricted foot position with the symmetrical bugnet- so the lay should be just like a hammock without footbox and attached bugnet ie. traveller or a HH with asymetrical bugnet
except you do have a net that doesnt get in the way and doesnt touch your feet
