How is wine a desktop application?

"Wine is a compatibility layer capable of running Windows applications
on several POSIX-compliant operating systems, such as Linux, macOS, &
BSD"

Having type=desktop-application for wine is just wrong, sorry.

We show more than just desktop apps... codecs, runtimes, fonts, etc.

Define "there"? If we're using gnome-shell we're asking the shell to
do this for us rather than stat'ing a file in /usr/share/applications.
In a sandboxed world we might not even know all the places .desktop
files could possibly be.
