Yes, thank you. That would go in the list of common EXIF issues, not
specific to PNG.

Right. And that is not even the only EXIF problem that is not
PNG-specific. I might as well split the article it in two: one part
with general EXIF caveats, and the other part with PNG-specific issues
and motivation behind our design decisions.

I found that people are generally more receptive to what I write if I
keep my content short. It's a challenge in this particular case,
because there are lots of things to be mentioned. But splitting the
content in two might do the trick.

Sincerely,
Cosmin
