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.
EG your GPU and monitor both have a USB-C port. Plug them together with the right USB cable and you'll get images displayed. Plug them together with the wrong USB cable and you won't.
USB 3 didn't have this issue - every cable worked with every port.
I believe the problem here is that you will have PNG images that “look” like you can open them but can’t.
Labelling is a poor band-aid on the root problem - consumer cables which look identical and fit identically should work wherever they fit.
There should never have been a power-only spec for USB-C socket dimensions.
If a cable supports both power and data, it must fit in all sockets. If a cable supports only power it must not fit into a power and data socket. If a cable supports only data, it should not fit into a power and data socket.
It is possible to have designed the sockets under these constraints, with the caveat that they only go in one way. I feel that that would have been a better trade-off. Making them reversible means that you cannot have a design which enforces cable type.
That's even more confusing than the current state of affairs. If my phone has power and data socket, then I cannot use power only cable to only charge it? Presumably with the charger that has power only socket. So I need a cable with two different ends anyway. Just go micro-USB at this point :)
Funnily enough, there is a 100% overkill way to solve such issues. Just use super expensive certified TB cables. Well... plus a A-to-C adapter for noncompliant devices, I guess.
Well, yes.
Why can't you use a power+data cable for the vape (or whichever appliance takes both)? What's the deal-breaker here?
The alternative is labeling, or plugging cables in to see if they do what you want them to do.
Both are a poor user interface.
