Yes, no, maybe, no timeline; apply to the questions as needed.
More seriously, most of these questions have been answered before, and for most, the answer is "yes, but there's no timeline for it yet. At some point, there will be plantable trees, a new economy, more hard-coded stuff moved into the raws (though actual fluids like water have more problems), multi-tile creatures have gotten experimented with, magic has been mentioned for the Artifacts section, the story was partially to highlight how planes could work in the game, etc
