To see whether there is more weigh toward a solution or the other, I would
formulate the question this way:

    are there real use-cases where one would want to *not* export a subtree
    (by tagging it), though to *well* evaluate the code blocks it contains?

If the answer is yes, then, definitely, both things must really stay
