dev mode provides enough for home-brew enthusiasts (running emulators and custom games/applications), and since you can side load such things, actually needing to bypass drm and security would be only for piracy, modding, and running alternative operating systems; linux and windows would be possible since it's x86-64 based, really the one thing i can think actually running linux or windows would be useful would be to use the xbox one as a hdmi recording and editing rig, possibly real-time video editing, but it's really down to no interest, legal issues, and cost, its not cheap when you break a xbox trying to reverse engineer it and now have to buy another one (few) , plus the equipment one would want isn't cheap either, that's why the past most console were hacked by people in college as part of a research project, where at a university they'd have easier and cheaper (well minus tuition) access to the expensive and good tools, or by a company who will profit from the exploit/hack *cough*team-xecuter*cough*
p.s it's interesting that team-xecuter started as a xbox hacking group selling products for the original xbox and 360, (Rocking the xbox since 2002 used to be their motto), and they went straight to switch hacking after the 360.
