Afaikt there's no news, sorry.

@Nate, Kevin: You seem to focus on default appearances. I don't think they would fix this bug, can you explain how?

For my understanding we need to extend poppler so that it can generate and save appearance streams into the PDF file in a consistent way:
- either generate PDF operations from user image to draw image as paths
- or rasterize / convert user image to a sampled PDF image
- create AP structure, enter the generated image stream, enter additional resources
- update all resource references throughout the document
- save new and dirty objects

That all has not much to do with default appearances. Even if poppler had hard coded default appearances for stamps, non-Okular readers would not benefit from them unless the appearance is saved into the file, which is currently not possible and which is the toughest part to implement. And, "default" is quite the opposite to "custom" (as in the bug title).
