The tokens are in the steem.dao account and my understanding is that there will be a process for the people who did not receive the airdrop to submit proposals to recover the tokens in the future. I intend to support those proposals assuming they are reasonable.
It is also possible for a single proposal to support airdropping the entire bunch, essentially reversing the exclusion in its entirety. If that's what Hive stakeholders want, it can be done.
It only takes one person (and 20 HBD) to create "for" and "against" proposals on this matter and we can see how the stakeholders feel about it.
