The code developed for this sounds like it could be a very interesting blockchain feature - a single DAO proposal which pays out to a large number of accounts. If I'm not mistaken, currently a given proposal can payout to only a single account. This sounds highly interesting to me because it opens up new avenues perhaps not explored before - a single proposal carried out by a large collective group of people who collectively receive funding. I guess it could be just a few or it could be hundreds of people.
Furthermore, another interesting feature would be the ability to hold the proposal payment in escrow and release it only when certain criteria are met (i.e. in the current situation the criteria are stakeholder voting on a proposal and witnesses updating their nodes to the new code). Again, the current second airdrop situation sounds like a use-case for this kind of feature, but I guess it would be done only one time (through a hardfork) rather than being a blockchain feature that can be used at will.
Yes, we're doing this as a one time hardfork, as the needs are somewhat specific (for example, it's not just Hive, it's also HBD, and it's a one time payment instead of something that pays out over time).
The proposal system could do with some improvements though, and we should probably setup a working group before too long to look into what should be done first.
