I have made version H by machine.
It was actually the first dress I made after coming back to sewing via the darkside and is just about ready for the bin now! I always wear clothes thin at the back at bra strap level and the fold of the fabric beside the zip has worn through, and also the zip is sticking.
I did it with conventional pressed open seams, but with hindsight the curved seams of any princess line dress are better with a narrower finish - overlocking usually, but by hand I'd do French seams. I also did a self fabric bias bound neckline rather than facings, but that would only work for view H.
