Because operating systems and application cliches should be separate! Layers that slip smoothly past each other precisely via well defined protocols of interaction. Now() is an outdated concept if we are to build systems that can age with grace.

That's all great and all, but why pick Gnome3 to rally behind? I literally know no one that can stand that desktop environment, and it has become part of this weird systemd/pulseaudio cult that is slowly destroying any chance of moving forward and producing a modern desktop environment for Linux that average people will accept, due to a constant (and ignorant) political war against pretty much anyone else that isn't part of that particular groupthink.

The irony here, I think, is Pantheon actually completed this goal with a much smaller team, with no political bullshit, and is a clearly superior product.

By virtue of this fact, and by your reasoning, Gnome3 has no reason to continue to exist at all and should end development if, truly, Linux is meant to have a One True Desktop Environment (tm).
