The retroactive benefit is fair but I seriously doubt that a manual rollout will provide that much benefit simply because the landscape is so extremely large, nearly every single fandom has multiple ways to identify any given work, small typographical differences can show up in the most unexpected places and I don't think a small group of developers can cover enough ground that most users will be satisfied or even regularly benefit from the feature. User suggestions could help but at that point you're creating labor to see what labor there is to make and asking of developers to make decisions for communities they don't necessarily understand.

To pick an extreme example, there are 32 mainline numbered entries in the touhou project series, every single one has a number, can be referred to as "touhou x" and "touhou project x", has a subtitle that can be used on its own or prefixed by either two previous options, has a more or less defined acronym ("eosd" is fairly distinctive, "um" isn't), and if you don't cover all of these for every single game in the series you're dividing how efficient your system is by a certain factor. Covering all of these options for all 32 numbered entries you are already looking at over 150 separate rules and that's only for the touhou fandom
