Nah, man, Miko was still raised and trained by the Saphire Guard, and a standing member of said order until just about the final moment. And for technicalities, I don't think they had the time to formerly expel her from the order. :P
Girard's defenses had a vulnerability that was exploited, but otherwise, he had nothing to do with its destruction. It's not his own trees that tore it apart. It's not his own rune that blew it up. It's not his own paladins that broke it. It's an outside entity that broke through the defenses and destroyed it. He was bested, but at least he, unlike the others, did not defeat himself.
This was pretty much going to be my reply. The only people aware of what the Godsmoot was all about are the people who were at the Godsmoot, all of whom are still there, with the exception of the Order of the Stick and the select few they told the story to.
And even in the odd chance that the Order was scryed on 24/7 and that Sirini learned about the Godsmoot from the Order explaining it to others, all gates had been destroyed prior to that point. So almost nobody knows about this threat, and no gates have been destroyed since those that do have learnt it.
Him getting control of the Gate now does not decrease the odds of the Gate falling when he is defeated. It increases it.
