Yes. DO NOT use submodules. I've been experimenting with them and they
are horrible. Instead, I would like to see, in addition to each of the
current svn repositories converted to git, an "ecosystem" repository
put together via git-subtree.
I put together such a tree using the existing git mirrors that looks
top-level (a git repository unto itself)
README (some general directions)
gcc (subtree of upstream FSF)
I would add test-suite in there once it's available via git.
We don't need the ecosystem tree right away. Better to convert each
repository by itself first. We can always build the ecosystem tree
I've got some formulas for working with git subtree and LLVM that have
turned out to work pretty well. I can post a tutorial once things

I agree with the individual repositories approach.
As I said, I would *strongly* suggest using git-subtree for this.
git-submodule is very unintuitive, to the point where I would not even
bother using such a repository. I would build my own using git-subtree.
