Add documentMode=source

I currently playing around with graphql-tag and graphql-tag.macro and ask myself. Why isnt there a
documentMode=source. This way I could completely remove graphql as client dependency.

I experimented with documentMode=documentNode but other then graphql-tag it did not generate a source property.

Rather I ask myself, why we need the documentNode? I only need the source to execute the query not the ast of the document node.

So I would like to suggest to add a documentMode=source with generates simply a string with the full source including a fragment for each query.
