--- Comment #11 from Dario Taraborelli <[email protected]> ---
I'm interested in following up on this bug, particularly for PDFs of vectorial
graphs generated from data analysis software (like R or Mathematica), which
researchers (including myself) routinely upload to Commons.

The quality of JPEG thumbnails for these PDF graphs is abysmal when compared to
a thumbnails for a native PNG format.

The only other option for vectorial plots to avoid these compression artifacts
is to upload them as SVG (which renders as PNG). However in many cases PDF is
the default export option and the most common format for scientific media
people will consider donating to Commons.
