I don't think it is a good idea to have file that can be both edited
manually, and auto-generated (i.e., tangled). Or, to put it differently,
the idea behind tangling is that you only handle the code block, not the
file itself.

You could add :tangle no on top of the sensitive blocks and remove the
flag only when you want to generate them.
