Image metadata is the wild west of structured text. The developer of the foremost tool for dealing with it (exiftool) has made 'remove metadata' feature but still disclaims that it is not able to remove everything.

How could that be possible? Isn't JPEG a fairly straightforward container for JFIF+metadata?
"Fairly straightforward" is incorrect. Not an authority to describe in more detail, but the most tricky blocker I'm aware of are these proprietary "MakerNote" tags from camera manufacturers, which are (often undocumented) binary blobs. exiftool might not even know what's in there, let alone how to safely remove it without corrupting the file.

But isn't it a contiguous sequence of data whose length is determined by the container format?
