Right, more specifically the `requires transitive` should never be 
different.

If there is use-case where the implementation is so different that it 
needs `requires` in the .extra file then it can be done but the 
augmenting would need to be done before the build computes the ordering 
that the modules are compiled (the modules are compiled in reserve 
topological order as Mandy knows).
