What do you mean? I haven't done anything to "bring this proposal through" and am happy with any outcome that the SPS stakeholders vote on. More than anything I like that the community is discussing and debating this and will ultimately decide the outcome.

As for the hive-engine account specifically, that's @aggroed's account and it's no different than any other staked SPS holding account as far as governance voting is concerned. I don't know why he decided to stake SPS there, but as far as I know it's not like it's SPS held on behalf of hive engine users or anything like that.
