This is a great change in my opinion. Nobody wants to give support and effort into dying projects

• There are other submitted Merge Requests to that gnome-session GitLab repository that are 3 years old and are still open. This is only a proposal, and doesn’t actually mean it’s happening.
• If GNOME developers want to focus on expanding Wayland support instead of maintaining X11 support, surely that’s their choice - they’re mostly volunteers anyway, shouldn’t they get to decide what they want to work on?
• If other developers still want X11 support, they can branch these session targets and X11 support code off into a separate package and handle maintaining it.
• X11 released in 1987. It had a great run.
