Re: [PNG] Meeting topics - Oct 27th, 2025

I would love your input, Leonard.
The issue/concern was raised in this GitHub comment
<https://github.com/w3c/png/pull/544#issuecomment-3417689319>.

I am trying to catch up on several things and haven't yet gotten around to
this. That is why I was vague and unsure when listing the discussion topic.
My hope is that it is a misunderstanding of what C2PA can & can't do.
