Not much he could do without grinding away the character of the stag. It's not uncommon to see in the work of many top makers.
Yes, it's much more difficult to do it this way, correctly. It's definitely an aesthetic choice, but like domed pins, once you learn to appreciate them, shit just doesn't look right without it. It's pretty easy to just "grind everything together", I honestly don't understand why people are so impressed with it. Building texture in layers on different, but parallel planes, is MUCH more difficult, and shows skill mastery, that many makers simply aren't exploring, or seemingly incapable of pulling off.
Obviously I feel passionate about certain construction techniques Ryu and I both utilize, so I'm a bit biased, but excellent piece. Very few of us are utilizing stag as well as he is, and where the hell is he getting it from? =D
Randy, as you move into more exotic handle materials, and especially if you decide to start utilizing exotic combinations of metals, you'll quickly realize how much they control the build. It's part of the fun. IMO though, anything that can tastefully add tactile feedback and dimensionality to otherwise pretty bland flat flush everything on an all stainless knife(not Ryu's knife, just speaking generally about plain-jane slipjoints), is a plus!
