The funny thing, I have installed some GNOME application that use the GNOME naming convention like “Archive Manager” (in addition to Ark because some exotic archives that work better with one or the other) or “Character Map” (because KRunner recommended that to me and not KCharMap), for example, and if KDE now does the same I would have several duplicate apps showing the exact same name and had to check the About page to be sure which is which, at least until memorizing its Icon and differentiate it by that.
That would have been your choice to install it. It wouldn’t be a default experience. Then you could go to the “Edit Applications” and change the name as you like
With a few manually installed apps, like in my case, sure.
But if someone new to Linux just installed a “GNOME Distro” and additionally wants to give KDE on the same System as well a try, or even the other way around.
Suddenly now having nearly everything, for someone new virtually indistinguishable, double in both Desktop environments at the same time, that would I (not) call a heck of a “Experience”.
