It took Podman a good 2 or so years to develop a good docker compatible http api. I presume that's why. There's no point in coming out with all of the features when they can release with some support, and add on top of it.
I hope there is something new. The tooling and deployment fragmentation is a nightmare.
From a security and open standards pov, we maybe should be moving to podman/OCI.
The docker tooling was often focused on the dev experience and it showed, but it wasn't a system with a good security model and this transition is a large part of that pain.
