How would that work _exactly_?
1. JDK-(N+1) is first shipped. The maintainer of JDK-N intends not to package it, so JDK-(N+1) includes Obsoletes:JDK-N from the start.
2. Someone revives JDK-N. Oops, it cannot be installed because JDK-(N+1) obsoletes it.
3. JDK-(N+1) is updated to remove the Obsoletes: . Oops, upgrades from older Fedora versions will no longer remove JDK-N for users who didn’t ask for the legacy version.
This is the problem that the renaming to -legacy is supposed to prevent. Though, perhaps it would work equally well to have Obsoletes:JDK-N < $version-($release+1); this would still allow updating the older Fedora with bug fixes for JDK-N but to be removed on upgrade, as long as the $release number is kept low enough. And the possible -legacy package could then be represented simply by shipping a version with a bigger $release.
