Interesting. I was not aware that was a thing. Orientation info seems way less useful in a lossless format like PNG. It makes sense in JPEG for instance because rotating and re-encoding would be lossy and slightly degrade the image.

See also: The VLC bug that incorrectly applies right crops as left crops [1]. This bug report is from 2023, however the bug has existed as long as VLC has as far as I know. I'm always surprised to see bugs like this where an extremely easy to test part of the spec just seemingly isn't tested and ends up as a bug that never gets fixed until many years later.

I firmly believe every product team needs to be split in two: one half works on the issue of highest importance, the other works on the easiest issues. If only to avoid the embarrassment of easy to fix bugs that were passed over for eons just because they weren't priority-high.
The way I've seen it implemented at a small company I worked at before was to explicitly endorse the "20% time" idea that Google made famous, where you may choose your own priorities for a fraction of your working time regardless of the bug tracker priority order. Even if in practice you don't actually have that spare time allocated in your schedule, it does give you some cover to tell your manager why you are prioritizing little UI papercuts over product features this week.
It gets even worse when ingesting images into Apple Photos, where you have to confront papercut bugs that you know will never be fixed.
I love ExifTool. It’s one of the great utilities. It works for almost every file I throw at it. But reading its output can be unsettling. It’s like getting a glimpse of eudaimonia, only to have it rudely interrupted by the reality of Apple Photos misreading every lens in your collection.

Why does a bug report get shared on hn?

The orientation data is defined as part of Exif. Both JPEG and PNG has officially supported ways of embedding Exif data. It's not defined specifically for PNG, but you would expect the Exif tag to work the same way regardless of image data format.
If this gets supported after the fact, aren’t people going to find some of their PNGs displaying upside down out of the blue?
If the EXIF data specifies a 180° rotation, then start at 0° and gradually increase the rotation by 1° per day until full spec compliance is reached.
