Mark,
Many architects either feel that way, or just accept that it is something to take advantage of when presented the opportunity. Pre-design, I usually feel that at least 12 holes can be built without any grading outside the tees greens, and bunkers. The other six may require varying degrees of major earthwork changes. In fact, since you usually need a place to put the fill dug out of irrigation lakes, I have twice had the problem of designing "too natural" of a routing without need to deposit 30-60,000 of fill somewhere.
It also applies, IMHO, to preserving the architectural intent or integrity. On gently rolling land, I would guess many, if not most, holes could move the fw bunkers down the fw by placing them in a similar upslope that was used to build the original bunker. So, if the landform exists to move a bunker from 250 to 300, most would use it to update the hole but keep the strategery the same. On holes where accommodating landforms are not available, the gca needs to take another tac.
BTW, I learned in SF at our annual meeting that the USGA keeps its course rating base distances at 250 yards, despite increases. First, even single digit handicappers have driver distances averaging just 258 yards. But wayward balls don't go as far, so any lateral hazard should be a bit less than the average drive, in their opinion.
