What registry mirroring options are not deprecated

So, i noticed recently that registry mirroring is deprecated for containerd.

In general, do people have best practices or examples of how they deal with the general problem of "I have a container image

image: projects.omg.com/hello:3.1

but it it actually lives at

image: mycompany.omg.abc/hello:3.1

Obviously there are dns tricks you can do , but im assuming theres a more idiomatic kubelet/containerd way to configure this ?
