In the end I assume this is intentional to keep the license issue of dtrace and ZFS in a dubious state. Thus preventing other distributions from shipping it. Meanwhile Oracle can ship it because they aren't going to sue themselves and the kernel folks seem rather uninterested in lawsuits as well (and even if they did then Oracle could drag it out forever considering that the company seems to have more lawyers than developers).
