Weighing in here - I personally do not think we need a second claim window.
Gitcoin has actively messaged around the claim window multiple times. If you were inactive for 30 days while GTC was the talk of the town, I would argue you are not actively engaged in the community.
If there are any recipients who missed the claim window but are still active, I would vote that we slot them into as Stewards and reward them through Seasons - rather than relaunching the whole claims system for those who are not even aware of it existing.
I very much resonate with making sure that everyone who created value for Gitcoin is able to earn in, but would suggest we focus attention on rewarding those who are engaged moving forward rather than those who may not be around any longer.
