I am not in the position to answer this.  But the combo "raw replace" is
problematic, I think, in that it is hard to say how much there is to be
replaced.  So I think some delimiters (as produced by :wrap) are
necesarry in the general case.

If I understand correctly, you want to nest blocks: A source block
nested in a results block.  I think, that is not possible.  So, for that
use case, I guess, another construct (other than results block) would be
necessary.

But other people might have the proper answer here...
