Yes it is tedious to correct oversights and mistakes of the past, but naming standard are important, as good filenames help with searching, and it's always useful to be able to identify content from the filename alone.

The fact that some wikis have lax naming standards is a shame, and those wikis are doing themselves a disservice, so hopefully this change will encourage many wikis to adopt naming standards now.


 * And this isn't just my wiki, it's literally every video on every Wikia in existence.

That is false. All videos on the wiki I use have sensible names - although the fact that Special:WikiaVideoAdd doesn't allow specifying the title certainly doesn't make it easy for people to use good names.

I've personally renamed hundreds of poorly named files, and use MediaWiki:Titleblacklist to prevent gibberish filenames from being used anymore. I have not actually tested whether Titleblacklist applies to videos, but I assume that it does.
