There is still some time till 2019, isn’t there? 
To be perfectly honest, I kind of doubt it will be implemented till then, and I am hoping we can enter 2019 even without it .
And while I too would like to see it (and don’t wanna talk for Anoek) I think the original idea behind OGS was to make it a great place to play classical Go. And whether visible or not (let’s hope not ) there is a lot of work to be done on that still, and I think it is a good thing not to divide attention into too many projects at once.
But yeah, I am pretty sure, that would require some backend work
