JPEG is the main format in which images are produced and distributed these days. Even cameras that produce "RAW" natively will usually have their output converted to JPEG for distribution.

No one disagrees with you. But for that very reason it's locked in supporting those old files. I.e. archival.
JPEG isn't going to morph into some brand new format that supports arithmetic coding. New formats will adopt those, specifically because they don't have to support decades and petabytes of files.
Not to mention, if you've ever actual written a JPEG decoder/encoder; the format is not conducive to coding outside of it's HUFFMAN/quantization format. PNG can add those things since it's actually an extensible format, but even then...why? It's not like the libpng everyone has installed will magically support them.
