Is it true that dub compiles everything in the source dir whether it's imported or not?

Yes probably because with DMD you only specify what you need 
compiling and RDMD actually parses the imports so it only 
compiles what is needed. As evidence suggests Dub compiles 
everything, which is slower and results in larger executables.
