No, I wouldn't, because my own preferences are towards immediate disclosure. Tavis Ormandy dropped Zenbleed out of the sky onto us. It wasn't comfortable, it was a scramble for us, but I don't blame Tavis for it; he made a principled call. Better that people know, than that information be concealed from them while designated elites perform a process.
I'd also prefer immediate disclosure, but I don't get how waiting a month without telling anyone is good regardless of which side you land on.
