Would we consider adding a constant (with caveat[1]) that is halfway between WP_DEBUG=true and WP_DEBUG=false?  One that is set true for new sites but false for upgraded sites, a WP_NO_DEPRECATED constant?  This way plugin authors would have most of an incentive to fix deprecated usage as their plugins would fail for newer sites that don't allow deprecated usage?
