Interesting argument there, but does this mean that we should also drop 
support for kparts in koffice and kjsembed from KDE? You could use the same 
core technologies to KDE to cause a security risk using a well crafted kword 
document. I agree with Tobias about this feature. Its a useful feature. If 
folks don't want it in KPDF, make this a compile time option and be done with 
it, especially since KDE distributes sources last I checked.
