The thing is, I also want to convert the dmd back end to D, and continue using 
it as a back end for DMC++. Some people want to use various parts of dmd for 
libraries.

Trying to push everything into the same file structure is not impossible, but 
rather disruptive.

Having this new switch means that users can independently adjust the file 
structure as they see fit on their own time schedule.
