I was thinking along the same lines, and I do like the idea. The fact
that folder name will not tell anything about the features used to
build the target is irrelevant to me. The subfolders today are just
used to separate different builds from each other, and guessing the
exact hierarchy that will be generated by bjam is almost as difficult
as guessing a hash value.
