Running official docker container as non-root user results in "Unsupported Third Party Container" installation method

Podman rootless seems the clear path on this, but I had to wonder if it was really worth the effort required to set it up and maintain.

This question came up after reading the page(s) about how to configure Podman to run rootless, and to also there being a need to run a docker-podman conversion on every new HomeAssistant image publishes.

Seems like the rootless setup of Podman is a one-time thing and not too onerous, but…
Is that image-conversion step truly needed every time HA releases a new one?
