Say you get a module from a third party, say jungerl. It doesn't have
the above attribute. How do you decide whether you should add the
attribute or not?

In general, you have to understand the code to be able to decide. And
that can be arbitrarily difficult.

My cure is worse than the problem. I should never have suggested it.
