I'd like to see this bit added somehow to the CSS Transforms spec.

Flash is treated as an overlay in Chrome, it's behavior with transform 
has been unstable, and it would've helped to have scale+translate 
specified as an "ok" alternative. Flash is still broken in Chrome.

I think we're going to need to figure out how to signal to the 
scripting/CSS environment when CSS transforms are limited to 
scale+translate (with rotate missing).
