@gargron Saw a somewhat charming approach some days ago. Instead of embedding the other post, the original post was shown prior in the feed, and the „quoting post“ as a response. This way it is possible to refere to another post in a direct way, but the initial post is still prioritized. This could be a good compromise from my view.
In this case this was a solution on the App side, which just worked when reply and boost were in the same timeframe.
