I think it would be interesting to see how detrimental (if it all) that settling would be to the trees on hugelkultur. In my case there is not enough wood to really make a difference. Most of the wood is to the sides. I leave a clear area straight below for any tap roots. So far 3 and a half years in there has been no noticeable settling.
