That's fine on paper, but the reality is that none of their "beta" products come with any real user risk.
I think it's more of a "test drive" scenario for google. It's fully baked but they want to see how it changes behavior on a wider scale where people make choices independent of the organization.
That's not true. Google has hosed large enterprise customers many times by rolling out new features or changes to existing products with zero warning, and they have adopted a phased deployment process and a formal trusted tester program to help mitigate it. Contacts is a waaaaaaay bigger deal for businesses than individuals, and there are tons of edge cases Google has to deal with re: Apps customers.
