Sometimes the software is split into several packages and the meta
package that would be used in CLI case doesn't contain a desktop file.
For example, USC advertise "eclipse-platform" as "Eclipse" while
people would use "s a-g i eclipse"
https://apps.ubuntu.com/cat/applications/eclipse-platform/

I'm not sure whether USC install suggests packages. If it installs
suggests package then there is no problem with "Eclipse" since there
is some sort of circular dependency.

Do you think "Browse C: Drive" is pointless for Wine?
https://apps.ubuntu.com/cat/applications/wine1.4/
Or "IBus Hangul Preferences" is pointless for Hangul engine of IBus?
https://apps.ubuntu.com/cat/applications/ibus-hangul/

Extra .desktop files is due to sometimes DE specific .desktop files are used?
As this the case for Synaptics.

How to "mark them to be ignored by USC archive-scanner", is it documented?
I hope such information available nicely in
http://developer.ubuntu.com/ while I understand such information can
also be figured by checking archive-scanner's source code :)

Sure.
