@kde No, it's not fine.
It's the worst thing to happen to Linux and any Open Source since as long as I have used Linux. 1994. It violates everything that built it to become as excellent as it was, now being piece by piece wrecked by this complete violation of the UNIX Philosophy. This slow infection killing user choice and compatibility just because a few developer elite refuse listening to the users is to be expected from GNOME, it's whar they are, but not you.
Letting it be A choice among many is as it should be but there is no valid reason for any DE to care how its DM was started, nor the DM to depend on any particular init, just as no distro not built for single use single task should be limited to only 1 PID1, only 1 shell, only 1 browser, only 1 App Store, as if it was an authoritarian iPhone. This is just objectively wrong, making it not just drastically more difficult to learn and to troubleshoot but also harmful and active creation of multiple times widely demonstrated single point of failure, abuse-enabling dominance which for certain if you let it advance to effective monopoly status will also let it become a tool for imposing political oppression with the worst possible consequences entirely probable.
It's not fine.
