To make my position extremely clear: I object to the premise of this proposal because it breaks core use-cases that we in Fedora and critical downstreams depend on. I would much rather us split the build tag and identify the set of source packages needed to be built for i686 and have that subset auto-built when the packager submits a build to the normal tag for it. That way it “looks” the same from the packager point of view, and the scope is drastically reduced for the content set for i686.
