cjpegli ignores sRGB ICC profiles about libjxl HOT 3 OPEN

sRGB should be default for JPEG and doesn't need to be explicitly declared. It saves 1 to 3 kB of data, and avoids simple programs loading the image slowly by applying a sRGB->sRGB conversion. Maybe there should be an optional switch. "Compacted" alternate sRGB profiles still trigger a conversion in the image viewer I use because it doesn't know they are practically the same.

Color managed environments use profiles, the default might be sRGB or something else.
What's strange is that the most basic profiles are not only treated as unnecessary, they are technically forbidden. If users don't want profiles to be attached, they don't add them in the first place - personally, I don't see any other way to think about it.

If an image does not have a color profile, it should be assumed to be sRGB, regardless of the environment.
