Thank you, Tom. At first I thought you managed to define a function that 
treats particular directories as safe (to discriminate own files and 
files having non-trusted origins). However in such case you would not 
need additional user option and `org-confirm-babel-evaluate' would be 
enough.

Walking through the passed expression to prove that it has no side 
effects is an interesting and challenging problem.

And frankly speaking, I was confused and believed that it is 
responsibility of the new function to issue e.g. `yes-or-no-p' prompt. 
Now I see that it is `org-babel-confirm-evaluate' that shows such prompt.
