Meh, not my thoughts. Those are the recommendations from the food science guys.
When you are packaging hops, you are trying to prevent oxidation of the acids and essential oils. As the alpha's oxidize, you loose bittering ability. As the beta's oxidize you develop a "stinky feet" smell. If you aren't vacuum packed and at low temperature, the essential oils will diffuse away and there goes a lot of your flavor.
Bear in mind that it is all about shelf life. As a homegrower we tend to treat the hops better than at a 300 acre farm. By the time a hop has gone from a field in Yakima valley to storage, it may have been abused by high temperatures, physical damage, and simple time before drying. So there for to keep their freshness factor up, they need to do a good job packaging.
As homegrower, we don't beat them up so they can take abuse in storage and still turn out all right.
