It's the only forum of appeals for deletion we have, it's being overrun, and with no forum to appeal a DRV, that's a major problem that needs to be solved.
I think one of the problems is that DRV is closed by just one, ordinary admin, with fairly wide discretion, so it only takes two (one for the AfD, one for the DRV) to come along and say, basically, "the argument I agree with is so brilliant and unanswerable that it trumps consensus", and the decision is made, with no recourse whatsoever.
