With r32816 the block and rights logs was added for user renaming. Please include more log types for renaming, for example the thanks logs.
All log types returned by hook 'GetLogTypesOnUser' are candidat for renaming in the same way as the block and rights log, because the user name is stored in the log_title.
Nice to have: Also add a maintenance script to clean up the old renames for the newly added log types.
