Good, question, as always, Johan - I will attempt to answer you.
1. Strictly speaking, I can build the hull without any FILLER blocks - as I have done with my previous build where fillers were only used for Bulkheads #1-3. It is thus well within my ability. BUT - I planked that with walnut and this will be with oak. I have never worked with oak before - I do not know how it bends, how it holds its shape and what percentage of spring back it has once all forms of clamps/pins and the like are removed. Instead of only giving myself the gluing area afforded by the bulkheads, I have chosen to go for planks that I can glue and secure along the entire length of the hull.
2. You mentioned "curvaceous". If you look at this picture below, you will see that the hull follows an acute curve from Bulkheads #1- 8. It is only after the planking wraps around Bulkhead #8, that it follows a relatively straight line to the stern. if I have filled between the first b bulkheads, I may as well include numbers #9 and 10.

3. All possibilities of indentations, kinks or dips in the planking are completely eliminated. Remember, I do not have the luxury of a double-planked hull - I get one shot and that is that.
4. It adds an enormous amount of rigidity to the whole model and also makes the upper ends of the bulkheads (from where they extend above the deck upwards) much more solid. This also means greater accuracy when planking above deck level.
5. This is basically similar to the authentic, bread-and-butter style building, pioneered by some very famous and yet to be emulated old-school Russian builders. I have always wanted to try this method (I regularly advise others to follow this method) and regarded it as personal challenge to incorporate on this model.
6. I have a two months' summer break now, so I do have some time (you are right, probably too much) on my hands.
