one thing is that the influence on standards will be pretty strong if you have the "main" implementation. So it requires trusting Google to go the right direction. You can contrast Google's "the web as apps" with, say, Apple + Safari's more "web as documents + prettiness" approaches. With at least 2 major implementations, even if Google doesn't want to do something, if Apple + Moz + MSFT does something, it's still possible to get it into the standard. You can try getting into the standard without a single implementation but that's probably difficult without a vote of confidence from stakeholders
