There are pros and cons to all possible designs, I think given the large amounts of money involved, it makes sense to invest at least something into developing a solution that is more specialised to the needs of the situation.
One of the big problems with DHF votes is that the proposer has zero idea whether anyone has even seen their post. They are then left wanting to promote it and risk triggering overly sensitive token holders by daring to try to communicate with them. lol
I think the best possible version I can imagine is one where the UI for proposals includes filters for common parameters (much more than we have currently) and stakeholders voluntarily submit their settings to a shared location to allow aggregation and for proposers to see the current state of the 'dhf market'. That way the system would also know which stakeholders to try to nudge towards voting through notifications etc.
I suspect such ideas are pure fantasy, given the history of the fund - but these are just some off the top of my head :)
