Even transforms added via javascript or onhover would be caught via live profiling.<p>The given use case of stopping flickering when a layer is created should be treated as a bug.<p>This feels hacky, and likely to be used erroneously or abused - at which point browser will be forced to smartly ignore leaving us with yet more cruft. Performance tuning is a fine art, and browser is in a better position to do it vs your average web developer.
