No, it's tearing down that wall because finally, instead of providing rather abstract system calls that are designed perfectly, the kernel can operate by providing useful libraries and apps. At least on the context i've worked on it has torn down walls and has improved the efficiency of working on ABIs towards user-space. (sysprof is an example of that) Kernel developers are finally faced with user-space development directly, in the same repository, using the same rules of contribution. Non-kernel-hosted apps win from that process too, as even if they dont integrate (because they dont want to or cannot for license reasons) they can participate in a more direct (and more practical) exchange with kernel developers. They can contribute a new system call and create a library function for it straight away.
