Reporters who only capture pictures on an iPhone and not a "real" camera, and who also never need to edit the photo to crop off or obscure identifying information, innocent bystanders/victims, gory violence or nudity, etc...
The problem is real, but this solution seems to not really solve it in any practical sense.
You want to do all that, then still can prove the picture is authentic. The editing history show what had been changed compare to the previous version, from the color adjustment to blur areas... it's not about preventing editing, it's about proving the authenticity when needed.

That's not a thing. Straight from Apple:
"When a photo is taken in the new Reference mode, the camera captures signed sensor data that Private Cloud Compute develops into an unalterable reference image. Reference images can be viewed in the Photos app alongside the main image"
So this only helps prove anything if you can share the original, unedited image. You can share it alongside an edited one, but you must also be comfortable sharing the unedited original if you want to prove you own an iPhone 18 Pro. Er, I mean prove it's "authentic"
Now I think C2PA had allowances for what you're talking about, but that also ended up resulting in it being easier to break.
You don't need to share the original image with everyone, just like how journalists don't share their audio recordings from interviews with everyone. You share with an editor. Or a court.

So, 90% of photojournalism outside of the major cities, then.
you could do edits like crops in a way that preserves the signature using ZK proofs
