The bugs are stacking up[1] and upstream only offers a paid version of 
pdflib-8[2]. It is my understanding that there is no way for us to 
package future versions and the bundled libs are vulnerable[3].

So, should it be removed? For more info, see the tracker bug for its 
removal[1], there are a number of rdeps that will require fixing[4].
