That would be really cool - too bad they'll never do it because they don't like people releasing private packs because it violates some mod authors' self-proclaimed TOS.
I've never seen the kind of proprietary attitudes about modding on GM sites or DOOM mods that I have seen with Minecraft modding. Not only does it hurt the community by ultimatel making modpacks more effort for the user than they should be, but it's also pretentious to make up and sometimes pay for copyright licenses when your work is automatically protected from theft under the same rules that protect fanart or other fan works, making it unnecessary. But I guess they also care more about the 2 pennies of adf.ly revenue from people downloading their mods from their links than the spread of their work in general.
Not saying they didn't contribute something wonderful, I love the work some mod authors do, but the fact some of them are so offended by modpacks that came into existence with the pure intent of making their mod compatible with a bunch of other ones baffles me, unless they just don't want their mods to work with other mods at all, which there are apparently some modders like that. (The BTW girl if I remember correctly? Didn't she remove Forge compatibility for this reason?) Granted, sometimes it's understandable like with Terra Firma Craft which edits so many things compatibility would be impossible and probably not enjoyable, but the whole disclaimer thing reeks of pretentiousness and overall distrust of the community, like they expect their work to be stolen. (It would probably be stolen as often as other fan works are stolen and they would be able to take the exact same action against it.)
