A lifesaver in specific circumstances!

The impact of this mod will be limited by the amount of advancement that need to do checks, which it optimizes.

If you have a cobbled-together modpack with something such as Blaze and Caves Advancement Pack, the performance hit is absolutely noticeable, opening chests takes visually longer, and this mod can turn this scenario into something stable. In this way it can be an obvious lifesaver.

It comes with a downside of that advancement triggers can be slower to trigger, and sometimes seemingly failing to trigger at all. This isn't that much of a problem unless its a complex trigger, and therefore advancement, not getting your fancy advancement sucks. This can also cause issues with mods that rely on advancements for progression gating, such as Spectrum and Pastel (and more specifically the APIs the rely on, Databank API and Revelationary API).

A useful performance mod, yet one with a gameplay impact. Rating it 3.5 of 5, has its obvious use cases. As a player or pack developer you should approach this as a case of cost/benefit.
