As a minor segue, we know we can dramatically reduce the size of the stable
repo (and the stable clone.bundle) if we drop all branches and tags for old
EOL releases and move them to a separate repo (e.g. stable-eol.git).

I have suggested this in the past, but it's not a trivial change:

- it requires a fair amount of git work
- it may disrupt some of the build infra around the world still building EOL
  kernels (for whatever reason)

In my preliminary tests, we easily dropped the size from 4GB to under 3GB.
