Yes, we prefer header units for the time being because it can be implemented with minimal sources changes and gives moderate compile time improvements. Also it should open future path to named modules. Also with header units we have some flexibility how to compose modules. In our experiments build time perforce significantly depends on number of modules required for compilation number of AST nodes that are merged.
