Reduce scope of 1.0 and make that release
I've had a look at https://gitlab.com/groups/xonotic/-/milestones/3 and IMO there are plenty of tasks that could easily be postponed for 1.5, 2.0, or in cases like xonotic-data.pk3dir#1125 even removed completely from any milestone.
From a player's point of view, a sub-1.0 version number suggests that the game is an unstable beta. In an age of live service games, post-release content changes are expected.
