The only reason that it has funding is due to @smooth and @blocktrades voting it.

This is false. There are many other voters. If I unvoted it, for example, it would still be funded (which would not be the case if @blocktrades were the only remaining vote).

Furthermore, if either or both of us changed our vote, there is no way to know how other stakeholders might respond by also changing their votes, potentially changing the outcome yet again.

Your conception of how DHF voting works is a bit off.
