I think this might because you are an advanced user who understands
package management. Do you think $User who wants to install KDE really
cares that he needs to install libqt kdelibs kdepimlibs libkde
kde-konqueror kde-kget etc etc?

I'm not so sure seeing pattern content prior to selection is necessary
for non-technical users. The result of potential installation can be
displayed post-solve as the API permits.

I knocked up a quick functional pattern selector in YCP that operates
in this manner:

By the simple pattern selector do you mean

? I have to admit I haven't seen it used on its own like this, do any
modules use it?

This would not be an issue if it were entirely implemented in YCP.
