I don’t see any such number in the Temp Check thread: ENS Public Goods meeting (may 10): should we use part of the unclaimed airdrops to incentivize core ethereum developers?
In fact, I see that the initial Temp Check suggested 10% of the unclaimed airdrop. The current draft has significantly reduced that to 3.7%.
If there were subsequent discussions/decisions in a WG meeting, then it sounds like those were not communicated in the previous Temp Check post.
For what it’s worth, yes, I read the numbers in this draft. And I agree with them. Please don’t jump to conclusions about other people jumping to conclusions. 
I would also be on board with @AvsA’s suggestion of 500k with different vesting periods!
Well I would love to hear your side of the argument! This seems like a very worthwhile use of the ENS treasury to me, in-line with Article III of the DAO Constitution as well.
