"If steeping is so good" makes absolutely no sense.
Some of the large vendors do send pre-steeped. Steeping only means aged until the flavors are stabile. Whether that point is good or bad is up to the user. If you have a flavor that you think is great as soon as it's mixed but bad after 3 weeks steeping would be bad. If you have a flavor that isn't good until 3 weeks steeping is good.
I want my DIY to be steeped and good so I can mix it ahead of time and not have to worry about finishing it fast or dumping it out.
