This worries me. Because presumably, changing the compression algorithm will break backwards compatibility, which means we'll start to see "png" files that aren't actually png files.

It'll be like USB-C but for images.

Does usb-c spec break backward compatibility ?, a 2018 macbook work perfectly fine with 2025 usb c charger

Yeah, I also don't think they've broken backwards compat ever. Super high end charger from 2024 can charge old equipment from 2014 just fine with regular 5V.

What was broken was the promise of a "single cable to rule them all", partly due to manufacturers ignoring the requirements of USB-C (missing resistors or PD chips to negotiate voltages, requiring workarounds with A-to-C adapters), and a myriad of optional stuff, that might be supported or not, without a clear way to indicate it.
