You could customize a style for your diagrams and then include it via a one-liner in every diagram you create. This also allows for branding of diagrams. Personally, I'm a huge fan of the simplicity and whenever I present such a diagram to teams or execs, I break the ice by warning them it'll be "ugly" or "let's go back to 1995 for a sec" :) More importantly, the focus remains strictly on the content because of the basic design.
