Case in point: Mezz creates Just Enough Items mod for MC 1.10.2, which has very few of NEI mod features. Obviously he developed this mod because he thought it was a good idea. Along comes ChickenBones and writes an NEI addon to JEI. I suspect some fans wanted NEI features back, else he would not have written the addon. Something as well accepted as Not Enough Items mod, which has become a very useful tool in mod pack development should either get a good consensus or be more flexible. In other words Chickenbones should have keep the original NEI intact when updating to MC 1.10.2, along with the JEI addon. Whether or not Mezz had good reasons(technical or otherwise) for the JEI mod is irrelevant to the fans. Just because you are updating your mod to a new version of Minecraft does not mean you can expect to have freedom to make changes without answering to the fans in some way or another. There are many mods, out there, somebody thought was a good idea, written without consensus, with the authors failing to understand why very few fans agree with them or issue a lot of complaints about it it one form or another.
