Shapes and/vs constraints

One of the differences between the proposals put forth by Holger and 
Peter is whether there need to be both shapes and constraints (Holger's 
view) or just shapes (Peter's). This sounds to me like an important 
difference, but I need an explanation of why 1) Holger thinks just 
having shapes will not work and 2) why Peter thinks we do not need both.

A simple, clear explanation of each point of view would be very much
