Not an Omarchy user and use podman rather then docker. But is this not a docker issue rather then a Omarchy issue, docker should verify user permissions through the socket, it's quite bad that it does not no?
Sorta, but there is a reason that no other distro does this by default and that docker itself warns that doing this is effectively giving the user password-less sudo.
So this is a problem in Omarchy specifically since it does the dangerous thing silently and by default while everyone else tries to inform the user of the consequences.
