I just invested some of my stuff that I have sitting in the Hive engine into it. I am not sure if this is something someone would need to write up a proposal for and put it to vote. The only bad thing about that is the vote for proposals doesn't kick into effect for a while yet I think. I honestly don't know for sure. It would be interesting to see what kind of tokens the account is holding over on the Hive-Engine. Unless like you said they are just rolling those earnings back into Leo.
