All those requests to revert the removal are funny: you want Chrome to re-add jxl behind a feature flag? Doesn't seem very useful.
Also, all those Chrome offshoots (Edge, Brave, Opera, etc) could easily add and enable it to distinguish themselves from Chrome ("faster page load", "less network use") and don't. Makes me wonder what's going on...

Chrome has a neat feature where some flags can be enabled by websites, so that websites can choose to cooperate in testing. They never did this for JXL, but if they re-added JXL behind a flag, they could do so but with such testing enabled. Then they could get real data from websites actually using it, without committing to supporting it if it isn't useful.

Edge doesn't use Chrome's own codec support. It uses Windows's media framework. JXL is being added to it next year.
It can, that's why you didn't say "re-add jxl", but had to mention the flag, 're-add' has no flag implication, that pedantic attempt to constraint is somehing you've made up, that's not what people want, just read those linked issues
It has a flag implication because jpeg-xl never came without being hidden behind a flag. Nothing was taken away from ordinary users at any point in time.
And I suppose the Chrome folks have the telemetry to know how many people set that damn flag.

Is asking for the old thing to be re-added, but without the flag that sabotaged it. It is the same as "you took that away from us, undo that!" Removing a flag does not turn it into a magical, mystical new thing that has to be built from scratch. This is silly. The entire point of having flags is to provide a testing platform for code that may one day have the flag removed.
Actual users, perhaps. Or maybe concern trolls paid by a patent holder who's trying to prepare the ground for a patent-based extortion scheme. Or maybe Jon Sneyers with an army of sock puppets. These "actual users" are just as real to me as Chrome's telemetry.
That said: these actual users didn't demonstrate any hacker spirit or interest in using JXL in situations where they could. Where's the wide-spread use of jxl.js (https://github.com/niutech/jxl.js) to demonstrate that there are actual users desperate for native codec support? (aside: jxl.js is based on Squoosh, which is a product of GoogleChromeLabs) If JXL is sooo important, surely people would use whatever workaround they can employ, no matter if that convinces the Chrome team or not, simply because they benefit from using it, no?
Instead all I see is people _not_ exercising their freedom and initiative to support that best-thing-since-slices-bread-apparently format but whining that Chrome is oh-so-dominant and forces their choices of codecs upon everybody else.
We have been active on wasm implementations of jpeg xl but it doesn't really work with progressive rendering, HDR canvas was still not supported, threadpools and simd had hickups etc. etc. Browser wasn't and still isn't ready for high quality codecs as modules. We are continually giving gentle guidance for these but in the heart our small team is an algorithm and data format research group, not a technology lobbyist organization — so we haven't yet been successful there.
In the current scenario jpeg xl users are most likely to emerge outside of the web, in professional and prosumer photography, and then we will have — unnecessarily — two different format worlds. Jpeg xl for photography processing and a variety of web formats, each with their problems.
I tried jxl.js, it was very finicky on iPad, out of memory errors [0] and blurry images [1]. In the end I switched to a proxy server, that reencoded jxl images into png.
Both issues seem to have known workarounds that could have been integrated to support JXL on iOS properly earlier than by waiting on Apple (who integrated JXL in Safari 17 apparently), so if anything that's a success story for "provide polyfills to support features without relying on the browser vendor."
Also, all those Chrome offshoots (Edge, Brave, Opera, etc) could easily add and enable it to distinguish themselves from Chrome ("faster page load", "less network use") and don't. Makes me wonder what's going on...
