No.

To keep the backwards compability with the JSR-226 specification. If allowing all possible display values in get/setTrait breaks JSR-226 we need to keep the spec as is, if not I think we could allow all values. I'm not sure if this particular issue is considered to break compability or not?
The same script doing getTrait("display") running on a JSR viewer and on a tiny1.2 viewer would return different results (inline and block), is this concidered a compability break?
