In Tweak we have basically a fixed load order (==configuration) which 
originates from the configuration used in the original build. But the 
main reason for wanting to have a well-defined load order is that 
typically, if there are sets of cross-package changes, they follow 
already established dependencies. Meaning that if I change a base class 
to include a new property and then some higher-level code to use it the 
load-order simply ensures that by default we load the dependent package 
version first. It may work without the load order, too, but the way it 
is right now is just clean and simple.
