Reply to comment by ApertureNext in Google Chrome Is Already Preparing To Deprecate JPEG-XL by leo_sk5

You can't open JPEG XL re-compressed JPEGs with the code that supports JPEGs (that is basically omnipresent and will be supported for foreseeable future without any doubt). If you want your JPEG back, you have to decompress it with djxl first.

So, you still have to rely on JPEG XL specific code which can start to "rot" (due to various reasons) with time if nobody maintains it.

Exactly, so you aren't losing quality if JPEG XL ends up flopping and you need to transfer back to a more compatible format.

Browsers not supporting the format and now dropping support aren't helping.

You are not wrong, I was talking about the "some long forgotten DVD on the attic" scenario when you suddenly find that you used some unusual image format to store your data for archival purpose because, e.g., you wanted to put more images on that DVD and now you don't know how to get it back because the only software that supports it is some Linux CLI tool that requires compilation with right flags to make it work. Or something even more arcane, who knows.

See digital dark age, though I am not talking about intergenerational problem - seeing how fast technology changes today and how more complex it becomes every day makes me think that such problems can happen even within our lifetime.
