Query: good, but why in mono?

Julie Andrews is young and fresh on this CD, which is a delight. The performances are fine, though they lack the warmth and perception of her later recordings. My only quibble--why the heck is it in mono? It is a sparkling, digital reissue of a 1958 album, which was available in stereo; I have some of the tracks from the original disc in stereo and the separation of the sound is very good. Maybe it has to do with RCA licensing restrictions.
