Looks like the work sponsored by #Valve on #ArchLinux is, indeed, oriented towards making Steam OS compatible with remote attestation (as an alternative to a kernel-mode anti-cheat hypervisor).

not really. Foremost, we are interested in automating and centralizing our package build workflow and to lower the attack surface of this process.

(it's also a prerequisite to building for other architectures with less effort)

I'm not sure where you get the remote attestation topic from? It's not mentioned in that mail or the related projects.

Both projects are worked on by members of the Arch Linux community to enable the central automation of packaging on the distribution and is sponsored by Valve.

What Valve does or does not do beyond that has nothing to do with those projects or Arch Linux and is your speculation (so please don't try to put words into my mouth 👍).
