Well, have just d/l the latest build (but not tried) + watched the post 67 video ... and I think we're on slightly different pages 
This'll be brief, as am just about to go to bed.
The cube with sphere, roughly centred on a cube corner is correct setup, re what I tried ... and the result is as I got (with previous release ... haven't tried latest) ... but what I'm querying is whether that's what people want ...
ie Do they want ALL the edges that form the concave region to be hard, rather than just the boundary edges - leaving the 'inner' ones soft.
I'd consider the better / more correct result being the one where just the lines of intersection (as with Union result) are hard.
Rather than take any notice of what I think, tho ... ask Dimitri ... as he's the (main) one wanting H edges to be returned.
If the cube with a bit of sphere subtracted was smoothed - in the all Hard Edge state - it wouldn't smoothe correctly ... whereas it would (sorta) with just the boundary edges made hard.
I see the use of hard edges as a temporary / interim measure - to maintain the geometry created by using booleans - whilst a better way (bevelling the seam / join) is implemented ... in D's case, by retopo approaches to re-establish proper eloops / geometry
Having hard edges where they shouldn't be doesn't make sense - to me.
Until this is clarified - ie what ppl consider is the preferred / correct result - I can't see much point in doing any more messing around re this particular issue.
