I think a dislike button makes more sense for replies. It might just speed up the echo chamber effect, but people are already hiding, muting, and blocking those with opposing or intolerable replies. So, in some ways, dislikes for replies make sense. People already weaponize blocks, and I often hear stories of accounts getting unjustly banned because of "organized bans" where a group of users coordinate to block and signal to ban someone they disagree with. Plus, you can already mark posts as "not interesting," so it might not make much difference.
