So much of the advertising industry is so entrenched in Flash. It's a big beast to turn, especially when you consider that not just the last mile delivery servers need to support CORS and videos need to be in a compatible format (webm, please), but also the entire production pipeline needs to evolve their processes and tooling. I've been kicking and screaming to get more of our partners onto HTML5 for a couple of years now. I've met with some success, but there's an awful lot of hoop-jumping to get there. Many advertisers are still of the mindset that "HTML5 is only for mobile", if they're even aware of it. Maybe once this battle is won we can look at a smarter VAST standard!
