I tried to search English Wikipedia user rename log to find rename similar to requested on Commons (Guydrury to Ninetyone) and could find it only when browsing log.
I think will be good idea to introduce next changes:
- Ability to search arbitrary text in all log entries (Title is useless for that purpose).
- Date filter (start - end date).
T66184: Allow searching also by new/target name on moving log page
T3697: The way to search blocked usernames in block log should be clearer
