IMHO, this is not implementable for a simple practical reason: All the JARs 
we ship are built from source with our default JDK. They will in general NOT 
work on any JRE that's older than the default JDK. (A JRE/JDK that's NEWER 
than the default JDK can work though, e.g., the java-1.8.0-openjdk packages 
in Fedora 19 and 20. But we were already providing those.)

I'd say this proposal is very similar to my proposal[1] for libraries: the legacy JDKs can be useful for the user when facing with non-Fedora development. IMHO, it is fine, and even great, that no Fedora JARs will depend on legacy JDK. However, if there are JAR files which are useful for a developer, they can have a -legacy version too!
