I don't think this is as widely known as you believe: I use dockerd via colima so it's not a limitation I've encountered - if I had, I likely would've switched to podman wholesale instead of compromising my system.
Either way though, I would hope it's self-evident to most that taking glaring security holes in a single app (docker) & transforming them into glaring security holes in an entire OS is generally not desirable.
Exposing the docker socket seems like such a rookie mistake to. There's a good reason we've known about docker socket proxies for a very long time.
Also beside that they use ancient package alongside Archlinux. One of those being Chromium. It also used to use Chaotic AUR but now they just automate packages (every 6 hours) in their own repository without any maintainer intervention so it's still open for supply chain issues.
