As for Minetweaker, I don't think any pack shouldn't have this mod installed, even if it is just for altering conflicting recipes, as it makes life easier for server owners who want to change stuff, for example they want to allow players to be able to use ChickenChunks to load their bases, but don't want chunkload spam, so they can remove the main chunkloader, and add a "much harder" recipe for these, so that they aren't spammed... I may make this a small project of mine actually (making "server friendly" recipes - stuff that stops chunk loading spam, and removes common lag causes, such as people trying to spam endoflames/charcoal farms for mana)
