It's not really up to FTB to take care of block Id's in that manner as I understand it..
Definitely get rid of clashes and having 1001 copper spawning in your world is up their alley though
The part of the conversation I heard had to do with things like multiple identical items just because the names are different, like Copper ores in Unleashed, having two tech mods that produce the same thing with different names and each not being usable by the other mod's machines (Ore Dust and Ground Ore for example) and that a proper naming convention should allow all blocks of a given class to work with all mods' recipies. For example from personal experience there are some things you can't make, like stairs, with Natura Redwood planks that you can with other types of wood. The naming standardization should take care of such issues.
If a standard for Ore Dictionary naming is the result of Jaded's current work, any modders who conform to FtB's naming style now won't have a thing to worry about when numeric IDs are gone for good and any FtB packs should have a much greater internal consistency.
