Where's the fun (and challenge) in that? If everyone cooked chicken exactly the same way, wouldn't life be really boring? I think campgrounds are all built around natural terrain. Remove all that, and ... well ... you might as well park in a 50 plus RV resort in Florida! Flat, boring, cookie-cutter. No way. Personally, I like the variety... good and bad... it just goes with the territory!
And remember, there are many campgrounds that started 100 percent primative, as tent campgrounds originally. Over time, they expanded and upgraded in order to keep up with the changing demands. A tent site may have evolved into a gravel pad for a pop-ups in the 60's before air conditioning was a demand. Later, big rigs came in wanting 50 amp service and full hook-ups. They put the utilities where it made the most sense for the terrain.
Thus, the very reason why I carry about 200 feet of electric cord for the camper, 200 feet of garden hose, and about 75 feet of sewer hose all the time. When going to new campgrounds, especially outside your own state, you just never know what you'll get. Be prepared for all occasions and the layout doesn't matter. (My opinion).
