Whilst that does seem reasonable, what about all the other software that iterates over a directory? Some of that is surely not going to know about DT_WHT. Further, while that may sort whiteouts, what about fallthroughs? There isn't a DT_ symbol for that... Fallthroughs are 'really there' in the sense that they're positive, but they should take on the underlying object type - which in this situation we can't retrieve:-/ I wonder if it would be possible to require filesystems that can store fallthroughs to store the lower type in the upper dentry (ie. there is no fallthrough type per se, but rather fallthrough-to-file, f-to-char, f-to-sym, etc.).
