Hey, I know you want to see RC delegations happen so I thought you'd be interested in what Steemit Inc devs said in their latest MIRA post:
"RC Delegations are a part of the SMT specification. SMTs themselves do not have token balances and will require their communities to delegate RCs to them to support maintenance tasks. The system to delegate RCs to users and SMTs share a lot of code."
picks up jaw that would be the nuts!
I know right? It was kinda of a HOLY SHIT moment for me too. :)
