So it means that the GNOME project will provide the libc? Because the parent comment says that GNOME runtime will be provided by the GNOME project. This would make the distributions redundant - which might not be a bad idea...

You are right, what I said didn't sound right, I re-read the proposal and there are several levels which are related so this is better abstracted. So you have a root filesystem which is unique and you can have several of these, they depend on a /usr filesystem which is from a distro and is shared and is a dependency of various runtimes which are shared infrastructure that apps depend on, additionally you have frameworks which are the devel libraries for building apps against. I'll have to read through again but it might also be that runtimes are supposed to be able to run against multiple different /usr distros but that doesn't seem possible because the ABIs of the /usr are different.

Actually I'm wrong in that the runtimes are mounted at /usr, and need to be at least complete enough for everything in the runtime to work as well as any app which depends on the runtime, so it seems to me that runtimes will also have to be full distros or based on a full distro.
