This is a feature that has been common on Tumblr, Discord, etc for quite some time. It's useful for chiming in on a discussion in a way that your continuation becomes new content on your own page.

I know a lot of people are worried it will be used toxicly, and it will, but like with all things Mastodon, we have so many methods to contain that, including letting users and admins disable it, and systems which slow the spread of toxicity (moderation, filters, decentralization) rather than speed it ("the algorithm").

A worse situation is what WILL happen if it's not added to the central repo: someone will make a patch which implements it on the server level, and we'll see servers with their own internal system that isn't linked up to greater fediverse: you will have no control over who embed-quotes your post, and may not even be able to see it happening.

This isn't #birdsite. Don't assume it'll be the same.
