This is a “there’s already a solution, but the average consumer wouldn’t know about it, because the defaults are made for them” type of problem.
One could claim that it's a UI problem, and should be exposed in the Camera app. This may be true, but the files are 10 to 12 times larger, with a real "quality hit", as perceived by the average user, for overall aesthetics. I personally think it should be in the settings menu. It's not something you would want enabled without understanding and intent.
It’s a little frustrating that apple added this feature, for this exact kind of thing, and they’re, inadvertently or not, getting a little dumped on, do to lack of knowledge/research.
These features (Google also attempted to standardize it, not sure they succeeded) were a big deal in the photography world.
