Hi, we do have different set of keyword arguments involved in pages and documents. There are page-wide parameters (like the paperformat, centered, fittosize, etc.) and document-wide parameters, like the mesh_as_bitmap or text_as_path.
In the canvas-methods we pass keyword arguments to the page, not to the document. To influence the document parameters, you thus cannot (currently) use the canvas-write shortcut methods. Regarding your N.B. comment --- could you please explain it again? I don't understand what you mean.
