Missing Windows Server 2019 Image

[crossan007]

These images don't seem to be compatible with Server 2019, presumably because they are based on Server 2016:

traefik             nanoserver                  353cb508ac13        2 weeks ago         1.24GB
traefik             v1.7.6-nanoserver-sac2016   353cb508ac13        2 weeks ago         1.24GB

Trying to run either of these images on Windows Server 2019, and I get:
