I think we’ve agreed that IE9 is now the oldest browser that FlexJS will support in terms of JS output. The original motivation was to get enough SVG support to do the graphics/skinning. Folks needing to run something on older browsers can deploy the SWF version since those old browsers probably have Flash.
If we’re going to make IE9 the baseline, should we start using Object.defineProperty instead of set_ and get_ functions? -Alex
