Though I do not dare enter the realm you describe, I applaud your quest for a go-based X11 ecosystem and hope you find considerable help from the go community to at least accelerate your vision/model to a proof-of-concept.
You may get the usual off-handed opinions when golang is involved - "Rust ...", "Yeah but Go doesn't ...", etc.
I do wish you had a timestamp of your article for reference in the future.
Cheers
