If you think about it it is not that strange... All data is always initially captured in raw by sensor and transferred to a processor. Which in turn usually compresses it to jpeg file according to a set algorithm. So in theory you would always have a raw file, just it was not accessible in the past and now it can be saved on the phone for later editing :) But yes, psychologically it is interesting, like a phone camera pretending to be a professional DSLR as this function used to be exclusively professional :)
