...but on second thought it's of course not a good idea to embed the raw image (likely several megabytes) in the authenticator data. Luckily we could still embed the raw image bytes in the client extension outputs, and just a hash of that in the authenticator extension output. This would probably mean that only platform authenticators can implement the extension in practice, but that would likely be the case anyway. So this should still be possible to implement within the extensions framework.
