Generally speaking I agree but pre or instamine is only a short term incentive. A kind of "tax" would be a better approach, as that would be a real incentive for long term dev involvement.
Better yet, post-mine or at least parallel-mine. If we know that, for every 25 coins paid out, the development team is getting one or two of those coins, then they at least have a stronger incentive not to Pump&Dump. Ideally, those who create the altcoin should get the last 10% of coins mined. That would maintain the strongest incentive possible to maximize acceptance and the stability of their own product.
