 Replying to [comment:15 SergeyBiryukov]:
 > The suggestion in comment:9 was to add a filter on the return value of
 `wp_attachment_is_image()`, to allow plugins create thumbnails for PDFs or
 other file types.

 I missed the point here. Let's re-open this. That would be cool to
 support. I think the focus of this ticket on the
 `wp_attachment_is_image()` is too narrow, and adding filters here
 shouldn't be considered. This function has one job and is doing it
 perfectly. Let's open the floor for other options.
