In case you are unaware, Datapacks are an upcoming 1.13 feature that bundles the power of command block creations, structures, custom recipes, and more into an easy to install zip file. They are basically server side scripts, and there is a lot you can do with them.
There are already several datapacks posted to curseforge, however so far they have all been shoved into the generic "Customization" category. I would like to see a dedicated category for datapacks. They aren't super popular yet since 1.13 hasn't come out and many are still in development, but they will have a big impact on the community as a whole in the future. (As an example, here is a datapack I've posted here on curseforge: https://minecraft.curseforge.com/projects/mechanization-datapack).
Also, many datapacks use a resourcepack for custom item/block models, so it would be nice to be able to bundle datapacks with a resourcepack somehow, or at least be able to mark them as a dependency.
