No and no.

I think there is a Consortium's document on "Levels of
internationization support in REx engines".  I think there are 3 or 4
levels, and we are on the first one now.  IIRC, what you propose is
similar to the level 2.

I would think that such things should be treated by pessimizers for
RExen: "mutate this REx to support composition/decomposition too".
