You're free to claim that, but my experience differs, so it's very likely
that we won't agree about this.
An example with a truncated package description:
Name : ImageMagick
Group : Applications/Multimedia
Description :
ImageMagick is an image display and manipulation tool for the X
Window System. [...]
ImageMagick also includes command line programs for creating
animated or transparent .gifs, creating composite images, creating
thumbnail images, and more.
ImageMagick is one of your choices if you need a program to manipulate
and display images.
The package does not include a .desktop file. Using GNOME Shell search,
it is not locatable when entering "Image" or "Magic". This is confusing
users. Examining the package further, it turns out the "man ImageMagick"
manual page mentions:
The functionality of ImageMagick is typically utilized from the command
line or you can use the features from programs written in your favorite
programming language.

We cannot start GUI programs from the command line when the DISPLAY
variable is not set or invalid. ;-p

I don't refer to "launching CLI programs after installation", because
that is _impossible_, and only having users stare at the --help output
in a terminal window would not be a great feature at all.
I recommend that anything that is installable via a GUI package tool (or
application installer) offers the option to _either_ start the installed
thing as the next step (which is feasible, if it's a GUI application) _or_
to continue with a jump to a system settings tool where to configure the
installed thing (e.g. a service, daemon, applet), which is not a program
that would be listed as an installed application.
Conclusively, if it became possible to install "ImageMagick" via
"gnome-software", the installed software ought to register itself as
an ordinary application in the menu system (or applications list), even
if starting it that way would only open a Help browser that explains
how ImageMagick is supposed to be used.
