Even more, they are destined for certain environments. OpenStack
technically is not part of that, but works in a lot of cases as a
generic OpenStack is just kvm and virtio, the same as GCE.
And some parts are disabled simply because they are large and of really
uncertain use.

Actually I don't think this is true. Why would you use GFS if your
environment already provides a redundant shared file storage for you?
Or can use a distributed store like ceph, which does not require huge
kernel extensions and are way more resilient.

Azure supports it, GCE supports it as a preview. I did not find
anything about AWS.

I don't think this warants shipping GFS and/or OCFS. If you really,
really want it, use the generic image with the full kernel, which is
required for several OpenStack environments anyway.
