Jim and I hope it never will be. Parts of the trail have not been designated, parts of it that are designated haven't been built, and the parts that have been built are often not maintained. Because of the altitude and weather extremes, in many places that have been marked, the markers are destroyed within a year or two. This means that it is very easy to get lost, and all the CDT hikers that we've heard about do get lost, usually more than once. A CDT thruhike can be anywhere from 2400-3000 miles long.
Some hikers choose to do a lot of bushwhacking, others choose to follow a lot of roads.
Right now, everyone gets to choose what they want out of their hike - and there are a lot of variations. A fast hike usually means lots of road walking, a scenic hike is slower and usually more difficult, but more beautiful. Most end up doing a combination of official trail, alternate trail, road walking and impromptu bushwhacking, with a few side trips just for fun. No one will make the exact same choices that you make. You can't do that on the CDT, unless you do a lot of road walks.
