It strikes me that this isn't a consensus issue, and so you are free to add it to the client any time you like. We don't need to 'vote' on this.
There's lot of things that aren't consensus issues, but would be great to have votes on anyway. e.g. Take my earlier idea that in a block-race stakers would randomly select a block (rather than use the first-seen) to minimize the orphan-risk for honest miners who produce big-blocks. I don't think that's a consensus issue, but seems like it'd be crazy to adopt something without knowing what everyone thought?
(Or another good example is mempool policy in bitcoin (Current vs FSS-BRB, Opt-in RBF, Full RBF) which seems wildly controversial, but with the shilling and censorship around it, it seems impossible to get a feel for support of each)
Consensus issues don't need to be voted on either, nor is it particularly useful to do so. If there is consensus, it will be obvious. If there is a real need for a vote, there is very likely no consensus.
However, voting on development
priorities is useful, as a means for the developers to get some idea what coin owners (somewhat an indicator of coin users) think is important. No one really wants to work on things that aren't wanted.
