Disagree. First of all, Google's practices aren't the norm, and might not remain the norm. Second of all, merely making and supporting your app multiple times for different platforms using their different visual / interaction idioms is a large economic effect. Even with cross-platform mobile frameworks, unless you decide not to test / support platforms other than your main one.
Standards are good because they bridge this gap. C runs on everything, e-mail runs on everything, the web runs on everything. Mobile web, for the most part, runs on everything.
edit: For the record, I do think that the mobile web standards need more work, but they're quite good at this point, and adoption is much better than 2 years ago. I'd like to see open standards for push notifications, for example (apparently there is some work done: http://www.w3.org/TR/push-api/).
