Deryck,
I understand your concern, but just for the record, this *was* announced on the wikis, and in the case of English Wikipedia, discussions about how to handle this were going on for about a month (Wikipedia talk:Interface administrators was created on July 30th). As a matter of fact, stop-gap measures were put in place in English Wikipedia as well.
You can argue that we need better mechanisms for such announcements, in ways that would reach more admins quickly. I would support that idea. But I do not agree that this has "completely wreaked havoc". Also, if English Wikipedia still doesn't have a formal process for admins to apply, is it because 30 days is not enough, or is it that 30 days is all we can afford and that the wiki community should be more nimble in situations like this?
So let's have a healthy discussion about it that is not driven by emotions.
PS: In Persian Wikipedia, we originally wanted to just wait for ENWP to come up with the policy and then decide to adopt it as is or modify it further; having noticed that the ENWP process is too slow to yield a policy before the deadline, we devised our own processes, and we now have 7 interface admins (out of 33 sysops). So, I guess it can be done?
