I don't thin my bevels for the first few times I re-sharpen them, unless it's for a client's request.
All of my knives from Japanese suppliers come with a V-grind edge, or that 30/70 type with a 'hollow grind' on the obverse side.
One of the main reasons clients seek out a Japanese style knife is for precise, razor thin cuts which provide superior food presentation.
They've had Chicago Cutlery, Pampered Chef, Wustoff and the Boston Store, and now they want something "very nice."
Many times I hear the argument that other edges are good for rough work and wet rope. That is your choice in the end.
However I just bought a knife used by The Navy and Coast Guard, and I cannot think of organizations that are harder on knives and probably cut more wet rope. Their knives are V-grind.
