Bach is timeless, some of his music was sent into outer space, and the old astronomy joke goes one day, they would detect a message using a radio telescope that said "Send more Bach!". If there is life outside of Earth, no doubt there'd be demand for it; they just don't know yet what they are missing... More seriously, if people imitated the music of the Baroque period, it's perhaps more as an exercise to improve rather than a personal opus magnum that will be published, because that time is just over. The same may be true for imitating some specifics of Bach's style (Johann Sebastian, there are many other Bachs that are likewise recommended, e.g. C. E. Bach also wrote excellent organ music IMHO). However, there are also timeless patterns in Bach's music that invoke/exploit recursion, symmetry, variation, reference of others and self-reference that are perhaps mandatory if you want to write the best music ever - see Douglas Robert Hofstadter's seminal book on that topic (and many fascinating others), "Gödel Escher Bach - An Eternal Golden Braid" (Basic Books, New York, 1979).
