We are very picky in choosing supported formats: each new format is not an addition of a small plugin, but a thoughtful and large work to support all the important features of the format (also: color data handling, metadata handling, efficient parallel decoding of multiple files and/or single file in parallel, etc, etc).
As a general rule: we support only those formats that are recorded by cameras, hence the main list: RAW, JPEG, TIFF, HEIC/HIF.
The last thing we would like to do is follow the path of viewers of "500+" formats, each of which is not fully supported.
Therefore, we cannot promise anything regarding the requested JPEG-XL support.
