The newest status update I could find is this [0] but that's over a year old too. Honestly I would rather if they worked on providing ARM64 packages. I know about and use Arch Linux ARM but that's a completely different project with different people and even fewer resources, which often manifests in broken packages (right now generating initramfs fails without manual intervention [1]). I remember for a long time Arch Linux didn't have any build servers and packagers mostly used their own machines to build packages. Not sure what's the current state of things but if that's still the case, then it's quite understandable that not everybody has an ARM64 machine to build on.
