If you don't keep track of the high-quality originals, how much do you really care about having the highest quality?

That's what I mean by "tweener" solution. You care a little about quality because you don't want to lose any more that you already have lost in your jpg, but not so much that you're keeping track of the high-quality originals. It's not nothing, but it's also not a big deal.
