If it did, then good riddance. Linux is barely able to attract hardware vendors to write less-than-afterthought drivers as it is; let alone with, say, even more non-Unix OS flavors as distraction.

Things like Redox and Haiku may be interesting theoretical constructs, but without the ability to use Linux (or BSD) device-drivers, they're not generally useful to the free software community and we can only hope they don't draw too many resources away from more useful pursuits.
