Personally I don't like the flailed look on trees, but as others have said it's largely cosmetic. Dead standing wood too is part and parcel of a healthy wood, a wood needs dead wood of all sizes and in all stages of decomposition to be healthy.
In the 90's I had a job in Antrim NI, stabilising a cliff above a costal path. Part of the job entailed bolting around 20 metric cubes of basalt block and building a concrete buttress by way of a retention plan. Just didn't make sense to me; £25k of work to retain the blocks, versus £500 to drop them and around £2k to reinstate the double path and hairpin underneath. So I talked the engineer into it and we reallocated the balance of the £22.5k into other areas of the job where the council had been a little light in their estimation.
The face cleaned up like a dream and the path proved to be easy to reinstate. Local reaction was however a little more problematic to deal with. For all the world it looked like we'd wrecked the slope below, which held all manner of lovely, unique to the area, flora. I just couldn't make the locals see that come the spring all would be back to normal. The thing that caught the eye of course being a ruddy muddy and rubbley scare down the hill side, the track marks from the machine that picked up the big bits just lent to the apocalyptic scene. They just wouldn't believe me as their eyes were telling them otherwise. So, a bit of a bone of contention with the locals
The following summer I attended a pre job site meeting for the next phase, there in all it's glory was the slope completely grown back and looking magnificent as only the antrim coast can. Credit where credits due though, all my most ardent detractors (representatives of the local community council) made a point of letting me know that they'd over reacted and that we'd been right to do as we did, essentially we'd preserved the natural character of that particular spot, no bolt heads and no mass of concrete to detract from the beauty of the place. That earned me more than a few drinks in the local pub over the course of the next phase.
