Log pages are a pain. They quickly get too long to load comfortably, so people end up manually editing them to archive the information, but attributions of edits are lost when the next automatic edit overwrites it.
They can't be programmatically resorted or filtered very easily. And the upload log makes Special:Unusedimages rather hit-and-miss by linking to every uploaded file...
