So we can keep the feel of what our animators creating and what is shown in our html5 translated animation. I was just wondering what your thoughts are on adding a feature like this to the spec.

Given that the user-agent renders things as best it can using the available resources, why would either ask it to do worse than it can (e.g. match the monitor refresh) or ask i, implicitly, to do better than it can, and thus frustrate it?

I am sure I am missing something (especially when you quote a frame rate that is low enough to cause visible judder).
