"Get All Chat Emoticons" endpoint removed without prior notice?

When trying to access the /kraken/chat/emoticons endpoint, i get:

curl -H 'Accept: application/vnd.twitchtv.v5+json' -H 'Client-ID: xxxxxxxxxxxxxxxxxxxxx' 'https://api.twitch.tv/kraken/chat/emoticons'
{"error":"Gone","status":410,"message":"The API version you are looking for is in another castle. See https://dev.twitch.tv/docs"}

Why is this endpoint returning this error? Shouldn’t it still be up since v5 is not removed yet?

It’s likely broken rather than removed.

As it’s just tooooo many emotes to load properly
