A channels list of edge alone is the outer bound on where a package may build, so both packages were refused for rc and stable and could only ever reach edge users. The fast ring builds them natively for all three channels, each against its own base mirror, which is how the other prebuilt -bin applications here ship. The channels key has to go rather than sit beside the ring: package_builds_for_mirror checks it first, so an edge-only list would still block the rc and stable builds the ring asks for.
