I actually think that Flower child quit the forge because he didn't like that his mod was compatible with other mods. And because of the techic pack having it included before. He probably left the forge to make his mod completely incompatible so no one can make mod packs with his mod. Besides His mod is gets boring after a while on its own, am I right. The only reasons I like BTW is because of the awesome water/windmills, the buddy block, the hopper, millstone, hibachi, and cauldron. And I believe that even if minecraft includes the ability for mods to be 100% compatible with each other, with a ton of new empty Ids, flowerchild will still try to make his mod incompatible. But I will say that Notch made minecraft for the people who play it to have fun in there own way, whether that would be griefing, or adventuring, building, modding, or anything that pleases them. So what Im saying is that ALL mods should be compatible with each other no matter if the mod's creator wants them to be or not. Im really hoping that what ever the people at mojang are planning I hope they can get a modding API into the base code that would automatically make every mod compatible. If I could have any wish I would wish that I would be the one to make an api that does alot like forge,modloader,and every other api combined, but just editing one class. And in my mind it would compress every block ID into 2 groups Vanilla and mods. With their own folders in creative mode and TMI And yes I do mean that. I mean sure it most likely corrupt old worlds but the benefits. But I could believe that there is a way to make mods use ids, yet they would be decimal sized. Like if I added a block I could give it the block Id of 249.0005 and that would take up a fraction of the ids we use now. But I doubt that could happen. Oh well as long as there is MC nostalgia and backups for mods I can always go back to old versions of mods such as BTW and play with them like before.
