Yusef Lateef plays both oboe and bassoon. I also saw him play the Dulciana at a session in '05. It is not the kind of music we discuss on this board but he is a giant in the jazz world..
I would agree that any instrument is irreplaceable in the orchestra (even the triangle has its importance).
I cannot imagine an oboist/bassoonist being a giant in the jazz world. I am not that big of a jazz fan, but I have never heard of him before. Perhaps he is a giant in your part of the world, but not here so much.
