Let me introduce you to the magic of USB Power Delivery, an incredible standard that brought forth USB-C devices that can’t work at all with USB-C chargers, since they don’t speak the required protocol.
Slow charging is compatibility mode. That’s a tad better than not working at all.
Yay to the USB standards bodies, and the many non-standards implementers, I guess.
Oh wow, Mozilla reconsidered JXL support. They said no after Google pulled out, but “now” (well, since an entire year ago) they’re at half a yes again.

Edit: neat, it has recently landed in the Firefox codebase: https://phabricator.services.mozilla.com/D263393
Still behind a flag, but Apple seems to have decided for JXL, and Mozilla seems to have gotten their mind made up and following suit.
