DSLR market has pretty much stopped (rarely any new DSLR camera is released) as everyone shifted to mirrorless cameras. Camera manufacturers mostly added HEIF (Canon, Sony, Fuji) as the non-RAW image format, because they already have HEVC for video. Camera with a lossy / lossless 12-bit, 14-bit JPEG XL would definitely be interesting for many photographers. Not everyone wants to be forced to do a complete post-processing with RAW. JPEG is to limited (8-bit only) and HEIF isn't much better, while not having much support (especially on the web) because of the patent situation. |

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.
