Making a similar tweak for the avatar log is something we're happy to look at - it's fair to say that it's not as important as the others.

We specifically tweaked the account creation log behaviour as it was starting to become problematic (e.g. taking up 20% of RecentChanges in some places, with only a few of those starting to edit) - but it's still available, with all the normal info, on Special:Log.
