What advantages does this offer over Darktable, the long standing FOSS lightroom alternative?

Edit: One criticism of Darktable is that it emphasizes its "scene-referred workflow" as opposed to a "display-referred workflow" like Lightroom does, making it not a true Lightroom alternative. Seems like this also happens to be written in C++ and also uses a scene-referred workflow? Quite the coincidence. How much of the important design decisions (or implementation) are just copied from Darktable?
