I'm going to take issue with this post.

Walter, you have completely misjudged what KDE is designed to do and are
blaming it unfairly. KDE apps are not designed to run in isolation -
they run in a greater context. That context is the KDE system.

It was designed with the view that an app like okular will be installed
alongside other similar apps that let you deal with other filetypes.
Like audio, video, graphics, text. And so on. To do this, it needs the
libs it is built on. And it needs a graphics toolkit - Qt. The reason
you got such a long list of packages to install is because you do not
have any Qt installed at all.

If you did not have any X installed at all and wanted to emerge xpdf you
would get a similar long list for exactly the same reason.

The point I'm trying to make is that KDe was not designed with you in
mind. KDE could never work for you because of your viewpoint and that
viewpoint is in your sig. So please stop blaming KDE for doing what KDE
does correctly and well. Just realise that you are not the target audience.

As an analogy most of the world wants a sedan so Toyota makes the Yaris
for them. You have decided you don't want a sedan but you do want a
crotch rocket, so Honda makes a CBR1000 you might like. Or if acting
like Rossi doesn't appeal, they also make nice adventure bikes. But that
doesn't make the Yaris wrong.
