I agree with the first part about credentials, but I see a bit of danger in how you view Github. I wish I had time to put more stuff in my Github account, but I don't.. All the work I do is for clients, or for my employer, and I can't post or share it. Sometimes I can extract a small piece and share it, but otherwise, I can't. I also don't have a ton of time in my life to code on personal projects anymore. So while I consider myself an experienced and accomplished developer (been at it for 20 years now), if Github is my "social proof via work product", then I don't look like much.. I'm not saying this is your fault or that people will only ever look at Github, but I hear this more and more ("show us your Github work") in the context of hiring and evaluating developers, and I hope it doesn't become just another thing that - following OP's point - people or systems hold against you for not having.
