I wasn't trying to imply that you're personally not familiar with the governance structure. I can see how what I said could be read that way, and I apologize for that. It was meant as more of a general statement...
In any case I've seen one technical issue escalated to Brendan so far since he resigned, after mailing list wrangling back and forth for a while got nowhere. He made a call on it (a compromise of sorts, as it happens), and people abided by that call from what I can tell.
He clearly has a lot less impact on decisionmaking now than he did before, which is what you see in his comments. I can totally understand why he feels the way he does. But I think he's underselling the importance he still has.
