I was pondering the same question recently. To me, that is the perfect design for a 36-ish-foot boat. Yet that's not what we see in new builds any more.
I don't buy the argument that the sleeping area is a waste of space. I like my comfortable berthing area, with full-sized, centerline, walkaround bed with plenty of stowage drawers, a hanging closet and en-suite full dry head. I probably don't really need the full tub, but it's a nice place to hang wet gear.
My saloon is plenty spacious, and the galley-up design leaves room for a very nice "guest room" V-berth with its own en-suite head.
For day use and entertaining, the saloon, sundeck and flybridge offer plenty of options, both dockside and underway.
I don't see how you could improve on any of this in a 32-40 foot boat. I've had boats where the master berth was a "cave." Cosy, but nowhere near as nice.
