Yes, I know, the kernel provides an almost complete and fully 
from-scratch reimplementation of the C standard lib. It would be 
almost impossible to rely on the libc provided by GNU, as the 
latter... relies on the kernel.

While reimplementing the C standard lib is simpler than 
reimplemented Druntime/Phobos, it could be argued that writing 
code using the libraries should be easier when relying on 
Druntime/Phobos, so this could be acceptable.

Problem is that D is needing those libraries not only for 
functions, but also for functionalities (of the language itself).

In C, you can use the language without a library, and I mean any 
subset of the language (yes, that will be a bare does-nothing 
application, but you know what you can rely on and what not).

In D you cannot. You have to avoid features *of the language* 
relying on Druntime and, worse, it is not even clear or 
guaranteed which of them.
