To ensure reproducible / clean builds, I thought makepkg would always be run in a sandbox/chroot environment. The damage done would be localised to that sandbox.

Ok. Devs could setup an option to pacman -U which allows it to bypass VT for privacy sensitive people. This just puts the onus on you to not ensure you aren't installing malware. The default Arch user should still be protected while allowing for your privacy needs.

Its too late then. People are already affected.

makepkg runs in a fakeroot environment, but this is not a security barrier. There is also support for building inside systemd containers, offering at least limited security, but most AUR helpers don't use that yet.

You mistake the target group of Arch Linux. Users are expected to read the documentation and to know what they're doing. Protecting users from themselves at the expense of those who know what they're doing is not what Arch is about.

That doesn't make sense, it's too late for people if new malware isn't detected by VirusTotal as well.

Goes against the very nature of the distro. I very rarely see assumed defaults in Arch, and they are almost always opt-in. Mind you, you need community provided helpers to automate AUR building, its that barebones and I'm sure there are people who manually build / use custom scripts to build every package.
It seems like you may not be familiar with Arch?
No, makepkg doesn’t run in a sandbox. The system tries to stop you from running it as root, but otherwise all validation of the trustworthiness of the pkgbuild and any sandboxing of the build process are left up to the user. This is part of why pacman, the 1st party package manager, does not fetch from the AUR.
Likewise, it would be generally against the Arch ethos to have the default behavior of the package manager interact with a 3rd party service. If a user wants that action, they’d need to perform it themselves.
