Yep! You just need to enable ‘Experimental Beta Support’ in preferences.

Nope, the CSS has to be patched, which is what Adwaita for Steam is doing.

Those are valid concerns, however privacy could be solved by support for encrypted DMs and posts. IIRC Mastodon has plans for encrypted posts and DMs, so it’s not out of the realm.
