Hi there,
First, yes i know normally podman handles all daemonless but at OpenWRT we do not use systemd so the default mechanism do not work for automatic podman healthchecks (like the restart policy).
First release works with about 30 containers with many different health check settings without any problems. Only one thing is spamming my logs which i try to handle as soon as possible:
conmon <container_id> : stdio_input read failed Resource temporarily unavailable
However, maybe some people can help me testing it a bit, or have a solution for the known problem..
so here we go 
best regards
