I see. There was an attempt to specify this property from Mozilla. IIRC they had issues with color managed Flash applications that blend into a HTML context and same colors didn't match between Flash and HTML. So far Flash was the only use case. IMO not a forward looking approach. If sRGB and DeviceRGB are the only property values and DeviceRGB maps to sRGB in Safari, there doesn't seem to be a reason to keep the property.
