I'm working on a datapack that adds compatibility between 2 mods, and because Fabric uses droplets instead of mB, the pack is incompatible with fabric. Could yall implement a way to specify that I want to use mB instead of droplets so datapacks that work on forge are compatible?

If you can't, is there any solution other than making a fabric version of the pack?

You should be able to use an overlay that only loads on fabric (see #3872)
