Depends how you define subsumed. The installed JDK does have...
/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home/jre
which wouldn't be a huge pain if they had created a symlink like...
/Library/Java/JavaVirtualMachines/jdk1.7.jdk
to point at the location of the currently installed JDK 1.7...
/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk
such that the symlink would get updated when an updated JDK 1.7 was installed.
