What I'd like to see here, and I think what's probably the general preference, is a single repository.  I've got nothing against having as many subdirectories of jdk9 as necessary, but they don't need to be separate repositories.  I'm not aware of any advantages to the forest approach, and it has some pretty annoying downsides (e.g., the project is less accessible to new participants; commits to separate subdirectories aren't serialized; work across multiple subdirectories is tedious).

(I do recognize that: i) this is orthogonal to the changes originally proposed in this thread, and ii) there may be technical challenges that make this a nontrivial project.)
