I understand what your saying but when your storing millions of images and transferring them frequently those small reductions in size are very significant when you get your storage and/or transit bill at end of month. A lot of the fluff and filler you mentioned is compressed and cached, so your not bringing it down every request and not in raw form. Even if you are sending a huge amount of uncachable stuff with each request it doesn’t mean savings wouldn’t be appreciated. It’s funds for a team lunch if nothing else!
