Absolutely agree that V berths have become downsized of late... generally the lengths are fine, but what's lacking is room at the bottom of the V for two pairs of feet. The low to mid 30ish foot French designs were the biggest offenders. As much as the finer bows are to blame, I believe that as they pushed everything to the ends of the boat to create (on paper) a good looking layout the V berth was crammed into the bow. A decent V berth, regardless of accessibility, "island" style, whatever, should have at least 2 feet of width across the foot. Many pinch down to a real V.
Our aft berth is a pullman of sorts, but access is only via the upper half, ie the entire inboard side is not open. Some contortions are required if the outboard person has to get up in the middle of the night, but we look at anything that requires some agility will perhaps help us to maintain some of that as we get older.
As for forward heads, I would agree that they're great from a layout perspective, and fine in port, but probably need to be backed up with a second head for use at sea.
