Is it possible for non-owners of a kernel.org account to do this?

Well, .git/objects for your kernel still consumes 121M.  It's not
gigabytes but I still wouldn't want too many copies of that lying
around.  Right now, I already feel slightly motivated to move the
whole content-addressable idea into the kernel.  It has disadvantages,
but the effect on disk- and pagecache-footprint for people like me
would come in handy.
