Fully agree with this sentiment.

Also good to know that Jpegli (a traditional jpeg codec within libjxl) allows for 16 bit input and output for '8-bit jpegs' and can deliver about ~12 bits of dynamics for the slowest gradients and ~10.5 bits for the usual photographs.

Jpegli improves existing jpeg images by about 8 % by doing decoding more precisely.

Jpegli allows for encoding jpeg images 30 % more efficiently by using JPEG XL adaptive quantization (by borrowing guetzli's variable dead zone trick), and the XYB colorspace from JPEG XL.

Together, you get about 35 % savings by using jpegli from the decoding + encoding improvements. Also, you get traditional JPEG that works with HDR.

Jpegli is predicted to be production ready in April or so, but can be benchmarked already.
