Any honey addition under about 2lbs will likely show absolutely no honey taste. Have you ever tried mead? It tastes as much like honey the same way wine tastes like grapes, or cider tastes like apples. The same way that wort tastes nothing like beer. That is, not very much. Sugar is what we really link the flavor of all of these products to. Once that is gone, we are left with something that may hint at the original sugar laden product, but not taste like it.
The flavors and aromas in honey are really delicate. If you want a honey flavor from honey, its best to add it to the kettle once you have cooled it below 150F so the delicate compounds don't volatilize. If you don't want honey flavor or aroma, just add it to the boil like any other sugar addition. In the latter circumstance, I don't see honey doing anything different than table sugar. Your weights will have to be different since honey contains a lot of water however. Since honey can be expensive, I only see people who dont' want to use refined sugars boiling it.
