I have no opinion on this fork, but note that keeping /usr separate shields valuable hand-edited configuration data (/etc, sometimes /root) from problems with the (much larger, and therefore more likely to suffer from e.g. bad sectors) /usr. (The usual "/bin, /sbin are statically linked, /usr/bin, /usr/sbin are dynamically linked" also makes it much easier to recover from some problems. Of course, putting stuff in /usr/etc/ or dynamically linking /bin makes these benefits moots - but that would be Doing It Wrong.)
