ForgeGradle (probably sensibly) yells at me about doing this. However: - There's a reasonable number of mods doing this, which establishes some optimistic precedent. - The licence update in Aug 2020 now allows you to use them for "development purposes". I guess source code counts?? - I'm fairly sure this is also compatible with the CCPL - there's an exception for Minecraft code. The main motivation for this is to make the Fabric port a little easier. Hopefully folks (maybe me in the future, we'll see) will no longer have to deal with mapping hell when merging - only mod loader hell.
