I’m working with a simple piece of cloth geometry in which I need to easily show a material/pattern on both sides of the cloth (as it flaps around …) Of course, I could “extrude it.” But, am I missing something?
Yes using the geometry node’s backface output and a mix shader node.
You could also use it to mix the base colour of one shader with the colour mix node.

Then I realized…
Intersecting terms always make me grumpy

yes, that word play had occurred to me too!
To be clear I meant the Input “geometry” node in the shader editor, nothing to do with “geometry nodes”.
