IMHO the central question is, if these should be "contextualized" boosts or just posts on their own, linking/embedding another post like we have it on #friendica.
On #birdsite quoted reposts keep a link to the original post for metrics so it became a special kind of reply. If it is just a quote, perhaps the quotee should get some notification (by mentioning) and the link is put below the comment. But those are just my two cents.
