What's the status of #stickers in #XMPP ?

I've found this #XEP [0] but it shows as experimental so I was wondering whether discussions were happening somewhere or if one can add a +1 about it somewhere.

I know it will sound stupid or just not a priority to some people but unfortunately, stickers are a requirement for many of my friends when it comes to #instantMessaging.
