Actually this poll is not accurate unless you know what the users are using. For instance Friendica has less users but all these features. As I run friendica.roelfrenkema.com too and fedilab to interact I would love to have these features.
@roelfrenkema Afaik Friendica devs introduced a lot of Mastodon api endpoints. They are really responsive. Some users using Fedilab created tickets for supporting some new endpoints. I would personally bet on Friendica supporting quotes before Mastodon does.
