since pdftex is supposed to behave consistently cross platform (same tex 
engine as well as pdf generation/inclusion behaviour), xpdf is the 
official pdf library used in pdftex (and luatex);

i share your observation with regards to responsiveness

of course one could use whatever library one wants but that's up to the 
responsibility of the distributer and not of the team; if it does not 
spoil the code base, multiple libraries can be supported, but as said, 
the de facto standard pdf lib is the xpdf one

we already had reports of users unable to compile pdftex because of dependencies of poppler (and no xpdf source being shipped) which imo is a bad omen 

anyhow, with regards to pdftex/luatex dev, the relevant library code is (to be) part of the source tree so that users can compile the standard distribution themselves 

(btw, i wonder how serious security issues are with respect to the used libraries - we use only part of xpdf)
