Yeah, but they left out that Chrome removed their own support for JPEG XL saying no one in the industry was in favour of it despite everyone seeing it was the future screaming for it and building support for it into their own products.

Chrome's blink was the only major browser engine not supporting it and that prevented it from becoming a web standard and they refused to acknowledge they were wrong.

Chrome only backtracked once jpeg-xl was subsumed into the PDF standard because if Chrome did not support jpeg-xl, they would by extension also not be supporting pdf.

Maintain in a sense. Google introduced it in Chrome as an experimental flag, then removed it with no real explanation, and only just brought it back.
