Given that there is already a spec for a control field that would provide architecture affinity for arch-all builds, I think that's a much better solution than implementing a separate control field for special casing packages so that they are *not* built on the buildds. Ultimately I believe the goal here should be that all binary packages installed on Debian systems should be reproducible builds. Things that get us closer to this - like ensuring that all packages in the archive are built on the buildds in pristine Debian environments, and that if they require building on a different build architecture this is declared in debian/control - are a good thing; things that work around this are not so good. Yes, we will need to support bootstrapping - which in practice happens far more often in corners of the archive (compiler self-depends, etc) than just when we add a new architecture. But I would argue that, as build profile support matures, even these bootstrap binary packages should be disallowed in the main archive, and instead only used as build-dependencies by the buildds.
