So, there's no real benefit from moving existing imports to this new MediaWiki page?

Scripts in dev.wikia mainspace are not reviewed for security, and some of them violate the TOU. Currently, most scripts wouldn't be accessible though MediaWiki:Import anyway  because they are not in dev.wiki's MediaWiki namespace yet.
