The DHF is a relatively small part of Hive's overall supply increase. Even though I agree there are plenty of funds there now (or would be, if the Hive there was converting to HBD, something that may not even happen with this release), I think it's important to have that little bit of long term inflation, so that there's an implicit promise that there will always be funding for development. More to the point, I don't think changing this factor will really make any real positive difference.
