I'm asking it because I've approximately 30GB of public domain scans in .pdf format to upload on Commons on the next months (see http://en.wikisource.org/w/index.php?oldid=928004#Royal_Society_Digital_Arch... for further information on it) and because I fully agree to the reasons listed on https://bugzilla.wikimedia.org/show_bug.cgi?id=11215#c3
Assuming that these are scanned documents that haven't been vectorized, have you considered converting them to DjVu format? Not only does Wikimedia currently have better support for it than PDF, but you might realize some file size savings. Apparently, there's software out there to more or less automate it.
Of course, that doesn't in any way preclude or remove the need for _also_ improving our PDF support. But PDF, as common and useful as it is, might not be the optimal format here.
