With .test thrown around a lot, would there be any complementary support from browser vendors for that TLD to be specifically a development tld? localhost is recognised to be one by chrome for example, that's the only domain where html5 geo api works without https, and "your passwords are transferred via plain text" is not displayed. In order to help shift to .test google might alter it's heuristics to recognise .test as a common tld used for development.
