Yes, but we shouldn't just cater to the lowest common denominator of

I would say that we need to - the majority of users use docker.
Granted, I don't have any numbers to prove that, but I've seen much more
"docker pull" or "docker build" in the wild than anything else.

Let's agree to disagree there.

I will not be referencing docker (or to refer to it as the only way
Docker Inc supports "the docker container runtime") in any examples or
documentation I ever write, nor will I be contributing to any solution
that only benefits docker (aka "the docker container runtime").

But I won't be taking any actions that purposefully inconvenience
docker (aka "the docker container runtime").

Which means that if it doesn't work with docker, doing it despite that would
fall in the "purposeful inconvenience" category, wouldn't it?
The conversion from intention to action is quite lossy.

I'm confused - you say kiwi doesn't support it, then agree with my
suggestion that we have it working already.

I meant that the pull commands you wrote there
("podman pull opensuse/tumbleweed"/"podman|docker pull opensuse/leap")
already work, not the aliasing to their counterpart without opensuse/.

If maps the /opensuse namespace as it's default
for the purposes of people pulling from, I don't
care how ;)

That's a misunderstanding: does not map anything.
The containers itself contain "opensuse/tumbleweed" as name.
Every container published below the openSUSE:Containers project is published
at the registry "root", as-is.

There is no such thing as a "default registry namespace" - it's a flat map
and official containers can place themselves anywhere they want to.
If we need aliases, those should be part of the container images themselves.

okay then, so no "podman pull tumbleweed" or "podman pull tumbleweed/$foo"

instead "podman pull opensuse/tumbleweed" for the Tumbleweed base
container and "podman pull opensuse/tumbleweed/$foo" for official
containers derived from Tumbleweed.

I'm okay with that.

I recognise that will work comfortably with the default registry of
that other container runtime also ;)

If you're referencing the "Hub of that other container runtime", nope, it only
supports a single layer of namespace/repository. So opensuse/tumbleweed is ok,
opensuse/tumbleweed/foo isn't.
"$othertool pull" should, though,
if the overlap isn't an issue.
