Just wanted to let you know that I’ve been actively working on this for the past week and am mostly done. It’s not quite ready yet though so you’ll need to wait a bit longer.
The solution here is that the WP Discourse plugin will be getting it’s own proper block for use in Wordpress’ new appearance editor.
This means you’ll be able to insert Discourse comments wherever you like on the post page using Wordpress’ new visual editor in themes like Twenty Twenty Three.
Technical Notes
This has been on the roadmap for a while. I had hoped to wait for the Block API to mature a bit more, but given the somewhat sudden drop in support for comments_template in the latest packaged theme, it looks like now’s the time.
