Write a script to import the data from user creation events in "Log events to all pages and users" (enwiki-yyyymmdd-pages-logging.xml.gz) dump into the local user table and local logging table. The user_id from enwiki and other data should be preserved. Perhaps practice on, e.g., https://simple.wikipedia.org/ (simplewiki) rather than enwiki since it's a smaller wiki.

The first priority is to mirror user data from user creation events (log_type = newusers) in the local user table; the second priority is to mirror user data from user renaming events (log_type = renameuser) in the local user table; the third priority is to mirror data from these log events in the local logging table. The lack of user table functionality is a potential blocker for bug 59618; the logging table does not appear to be a blocker for anything.
