Besides, how to detect capabilities?
Examing for specific dbus interface or using systemd?
I don't think this is a good idea suitable for "all" applications.

You can still do the additonal checks you like regardless of the DE name
Sometimes we really just need that "name string". Otherwise, things like
"uname" won't exist, either.
Sometimes you just need the name for some programs and there is no easy way
to figure it out.

Please explain what's wrong with it. It's quite useful for desktop
Not everyone writes source code for Gnome or KDE only.
There are programs which need to be usable across desktop environment.
If I want to know which program I can use to open file of a mime-type, I
query mime database.
Then I get a list of desktop entry files. If I don't know the name of DE,
how can I know which ones can be shown?

Isn't this what has been done in menu spec, a listing of known desktop
environments for OnlyShowIn/NotShowIn in the spec?
Everytime a new DE is created, we add it to the list. Is this ideal?

Then why a project like xdg-utils exist? It should be killed.
In the "free world", not every applications is designed to work with Gnome
or KDE only.
Not every program is bound to a specific desktop environment, either.
While I understand your ambition for finding the best solution possible,
it's not necessarilty the best for other small and simple projects.
Please leave room for others. We just need a simple solution to solve
If name comparison is not enough for your DE, you can still add more
complicated rules to yours.
Adding a common way to export DE name won't hurt anything. It only helps
people who really need it much.
