Why the push to remove Java 7 support as soon as possible (which is how I read your "cluster admins plan to migrate by date X, so Spark should end Java 7 support then, too")? First, I don't think we should be removing Java 7 support until some time after all or nearly all relevant clusters are actually no longer running on Java 6, and that targeting removal of support at our best guess about when admins are just *planning* to migrate isn't a very good idea. Second, I don't see the significant difficulty or harm in continuing to support Java 7 for a while longer.
