This is being done primarily to ensure consistency between the source documents and the final, rendered HTML output. Because member/feature/returns sections will always appear in a visually grouped element in the HTML output, prohibiting free paragraphs between those sections ensures ordering consistency between source and the final render.
Additionally, prohibiting such "middle" text paragraphs allows us to classify all plain text sections as either "intro" or "detail" sections, because these sections must either appear before structured elements ("intro") or afterwards ("detail"). This keeps the inlining algorithm simpler with fewer "splice" points when inlining multiple documentation blocks.
