This is bullshit. Something like AppImages can be done with bloody shell scripts.
xdg-portals are far simpler than the cluster fuck that is every Dev just creating their own solution, etc.
Solution for what? Let’s please verify that you even know what xdg-portals are used for, that is, that you know what you are talking about.
You keep saying that far more complex things are actually simpler.
You keep ignoring actual questions as if you were above them, you are not.
Where are you getting it from?
From knowing what those things are. I just don’t immediately remember any of the details, because there’s too much information in our lives and Wayland, Flatpaks etc are far from the top of the list, and more than that because I expect you to argue in good faith which won’t require putting facts under your nose.
Also you keep behaving as if someone owed you something in general or if they lost an argument. They don’t.
