I had thought not to enter this debate, but I would like to make one comment -- or rather to pass along a comment.
A noted French teacher, from whom I had the privilege of taking a few master classes, commented with regard to some modern French organ music, that the particular composer in question played his piece this way (and proceeded to demonstrate, spectacularly) but that I should take the piece and make it my own. I thought then, being in some awe of this particular teacher, that this must be very good advice. Perhaps more to the point, nothing I've learned, heard, or played in the succeeding five decades or so has caused me to change my mind.
The composer writes the music. He or she may have some rather definite ideas as to how he or she would perform it, but the artist who does perform it, assuming that he or she is an artist and not an automaton, is wise to find their own way through the music, so that it says not only what the composer had to say, but what they have to say.
Sometimes this may mean not playing much -- or any -- of a particular composer. You just don't speak the same language at all. I, for example, play very little Debussy. On the other hand, I play a good deal of Chopin. I find I can make wonderful music with Bach on an organ -- but not on a piano or harpsichord. And so on.
