No, or at least not yet. But if we know of only one user that wants this 
setup, surely that's not a problem?

By the way, you were going to evaluate the new default. Do you now think 
that it's problematic somehow (and, for instance, the previous was a 
better default), or do you want to change it as a purely personal 
preference?

Yup. These are the two options.

Well, if you're sure about that.

Having them all on the hook seemed logical to me, but indeed I don't 
know how necessary that is.
