I am changing the status to 'Stalled' 'External' per description of T204747

No local or global group is currently granted the 'usermerge' permission, making the extension also unused.

And per comment

In its current state, UserMerge isn't suitable for use on Wikimedia sites due to database performance issues, and poor integration with CentralAuth/SUL. These problems aren't insurmountable, but I don't think the time investment into fixing them is worth the ability to merge users, nor has anyone stepped up to fix them.

I would recommend/endorse undeployment until those problems can be resolved, either by improving the database schema so UserMerge doesn't have to make unindexed, expensive database update queries, or some redirect thing like Tgr has suggested.
