I think it is a bad idea. In general #*unspecified inside of a music expression is elided. (make-music 'Music) isn't. It prints under \displayMusic, it takes articulations. It has non-trivial side effects and should not be silently inserted for what may likely be lackadaisical coding without a clear idea of what is happening. -- David Kastrup
