Yup, it certainly happened.
They graded the beginning of the trail as you mentioned and the rock garden is now gone. But they stopped grading shortly after the waterfall . As you start climbing though, the trail is very challenging and difficult. Lots of boulders, rut outs, etc...much more so talhan before the fire
We made it all the way to the top, but probably would rate this as 3.0 minimum, more Ike a 3.5 for an inexperienced wheeler.
Fun and beautiful for sure though
