Sure, I'm actually surprised this hasn't come up before. :-P

But the CLA process seems to suggest that I have to add it as an alternative email to my main GMail account, which I definitely don't want to. Do you know if there's another process I can use?

Looks like an edge case where the solution was for me to manually override. I confirmed that you signed the CLA with this Github username with an other email address.
