IMO that defeats the purpose of using this format if you have to write things to compile to it. If you do that you might as well just compile to the binary format since you won't be editing your canonical representation anyway. I'd imagine with image formats you'd want to pick a format that is the easiest possible thing to parse and consume while not harming it's "editableness" and I don't think S-expressions fit that bill.
