That draft looks good to me!

Is there anything in place (like a popup after login) to draw attention to new posts in that section, though? Because I'm not sure I would notice it myself (at least not quickly).

If it's time-sensitive (i.e. the more people that notice it quickly, the better) then maybe it's a good idea to temporarily have a stickied post on the parent board (Bitcoin Discussion) that refers to the one in "Important Announcements"?
