Just to be clear I was not talking about "all" CSS features but mainly the ones specified in text/css stylesheets. New CSS features that are implemented through JavaScript APIs (like CSS Painting API) ought to be restricted, and exemptions should require an explicit compelling argument. Browsers have already invented mechanisms to expose properties conditionally so it's not an implementation burden, and it's possible for web developers to do feature detection and deal with it. The calculus comes out differently. [I note the CSS Painting API spec doesn't mention such restrictions currently, but Chrome's implementation seems to have done so anyway.] -Dan Veditz _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
