No, I still don't get it.

You also do not provide the "own version of lp/lpr". You expect the
apps that need a fileprinter to find it installed. Same would apply
for kdedoprint. (To the user it doesn't make a difference if that
kdedoprint utility is part of kdelibs, kdebase, or kdesomething. He
just needs to be told, somehow, "if you want to print from okular,
akular and ekular, you need to install kdedoprint".)
