Other than the Mobley and this Henderson, what other BN sets have they produced recently? Most of it seems to be from other labels, although most are ultimately owned by Universal. I think they stick with CDs because it's in their wheelhouse, financially and aesthetically in terms of what their customers like.
Wanted to add, my statement above regarding Bandcamp has nothing to do with any of the moronic reviews currently on the Mosaic site for this set. They should scrub that nonsense ASAP.
