The problem is that if the code blocks are non-trivial it slows down
the export. Changing one line of documentation and exporting
re-evaluates all the code blocks, which for me often takes several
minutes. The defaults work for trivial examples, but not my real-world
use. Since it's easy to make it work how I want it to via
org-export-babel-evaluate I don't mean to complain too much. I posted
mostly to make sure the OP knows about org-export-babel-evaluate, in
case disabling code block evaluation on export makes sense for them.

Yes, I agree about that.
