The January 2024 issue of IEEE Spectrum has an extended article on the subject. I recommend going through it and the links included; here are the most relevant parts for our question (emphasis mine):
Tessa Sproule, the CBC’s director of metadata and information systems, says [...] her team has been overhauling internal image-management systems and designing the user experience with layers of information that users can dig into, depending on their level of interest. She hopes to debut, by mid-2024, a content-credentialing system that will be visible to any external viewer using a type of software that recognizes the metadata. Sproule says her team also wants to go back into their archives and add metadata to those files.
At the BBC, [Laura Ellis, Head of Technology Forecasting] says they’ve already done trials of adding content-credential metadata to still images, but “where we need this to work is on the [social media] platforms.” After all, it’s less likely that viewers will doubt the authenticity of a photo on the BBC website than if they encounter the same image on Facebook. [...]
Bruce MacCormack [chair of Project Origin and a member of the C2PA steering committee] notes that the early adopters aren’t necessarily keen to begin advertising their content credentials, because they don’t want Internet users to doubt any image or video that doesn’t have the little “cr” icon in the corner. “There has to be a critical mass of information that has the metadata before you tell people to look for it,” he says. [...]
If social-media platforms are the end of the image-distribution pipeline, the cameras that record images and videos are the beginning. In October, Leica unveiled the first camera with built-in content credentials; C2PA member companies Nikon and Canon have also made prototype cameras that incorporate credentialing. But hardware integration should be considered “a growth step,” says Microsoft’s [Andrew Jenks, director of media provenance projects at Microsoft and chair of C2PA]. “In the best case, you start at the lens when you capture something, and you have this digital chain of trust that extends all the way to where something is consumed on a Web page,” he says. “But there’s still value in just doing that last mile.”
CBC's stated hope to start a credentialing system by mid-2024, along with Andrew Jenks's clear hint that such a system does not need to include the capturing stage (hence the lack of compatible cameras is not relevant) hint at a possible Yes resolution here with a probability higher than my previous 5% (and arguably the crowd's current consensus of 8%). Although I cannot easily imagine the benefits of such a scheme if it does not include the capturing stage, it would seem that a deployment in a demo/transient capacity in a way that will resolve the question here as Yes is not as improbable as it may have sounded until now (although "only" still sounds like a high bar).
If the runway for this question were the *end* of 2024, I'd be more inclined to put more stock in this statement (i.e. if we're aiming for mid-2024, it's more likely it'll be implemented in Q3 or Q4).
