I strongly suspect that if we could hear recordings of any of the famous pre-recording Western classical composers playing their own work, contemporary classical musicians’ immediate reaction would be “No, that’s wrong!!”
Even here, post-recording, I feel like the composer and his ensemble take stylistic and interpretive liberties at which musical authorities would turn up their noses now: https://music.apple.com/us/album/rhapsody-in-blue-original-1927-recording/400328499?i=400328513
