The files inside the src/main/resources folder were intended to serve as the default hierarchy (for programmatic use -- since files inside the data folder are not readable from inside the jar), whereas the files inside the data folder were to serve as templates for the end-user. I can very well delete the files inside data folder, but I guess it's in general a good practice to bundle up all the additional files inside the data folder.
