No. These two tasks are different from what I can tell. CU has its own logging system (not mediawiki core's logging system) so migrating to "the" new system doesn't make sense. But CU does have the mass blocker which still uses the old logging system for blocks.
It looks like this task is about adding gender support to CheckUser logs. I'm unmerging these two.
