What’s the difference between options 2 and 3? I mean, if we #+INCLUDE when 
tangling how is it different from including code blocks? Or do you see option 3 
as a more granular way to refer to external entities, something comparable to a 
programming language import statement?

Thank you, Dan. It could be a good enough interim solution.
