CRI material seems need to be updated

The 2nd paragraph said

The project is in early stage, with lots of development in action. Now that Docker-CRI integration is done, new runtimes should be easily added and swapped out. At the moment, CRI-O, rktlet and frakti are listed as work-in-progress.

Is this still relevant?

dockershim will soon be removed[1]. rklet[2] and frakti[3] are also retired.
Found reference for current container runtime enginers that are supporting CRI in [4].
