seeing as this is a tool to make mods run on both fabric and forge could you add a way to define costum modding API's
via for example modules so that for example you could write a module to allow mods for minetest's modding API to run on minecraft or via verse (and of course write a module to allow mods to run on any other modding API / voxel game ) (suggestion,roadmap) ?

no that’s too far fetched also not reasonable
we are not trying to be a full abstraction layer
