I just went to the poll to see if I could see who the other witness was who voted against EIP and it looks like there were actually 17 who did so and 22 who said "yes" to it.
However, you said "top" witnesses so maybe the people who voted were not the top witnesses.
If the are though, I'm wondering, how does the decision actually get made. Is it simply by majority. Would this small a margin be enough to carry it through?
Also, is there any easy way to see who is pro the changes or will there be a way to see who is going to vote which way closer to the time? Or are we reliant on individual witnesses making posts about it?
