I hope Mikrotik is looking at Facebook Wifi, currently supported by Meraki, Cisco and even Netgerr

Right now we have to hack the hell out of the walled-garden and completely open facebook (which kind of defeats the purpose as thats what majority of people want on the internet) just to get a facebook login.
I am very interested in knowing if you have successfully setup a hotspot login using facebook.
I have but not without opening the entire facebook.com domain
Will Mikrotik support this: https://www.facebook.com/business/a/facebook-wifi/businessowner
Many clients ask me about it, why do not use Mikrotik for this implements???
I found a Mikrotik answer from middle 2014
Hello,
currently we do not support this feature. We might reconsider adding this in
future.
