For vendor hat meaning full-blown systems, yes that is true, but for 
embedded, or even on some "real" platforms, that definitely matters.

Fundamentally, however, we're never going to have a full-blown libc 
environment built out of the kernel tree, as its size would be 
comparable or larger than the kernel itself.
