I think that would be a nice change to the DHF. As it is right now, I do think that there is a lot of spending and not much being added to Hive. It makes me wonder because of how hard Splinterlands's DHF proposal failed until some compromises were made alter.
The problem about the DHF is that the money is distributed for political reasons and not practical ones. It's more important what connections the creator has than what he is building. The way it works now is not fair towards all the users of hive who don't get the support. The dhf belongs to all of us and we should put some checks into place that the dhf really pays for things that bring value to the chain.
