I beg to differ. I think what is the sensible default depends on the
usage of the machine. For departmental mail servers, then you are
correct relaying is more sensible, but for "Satellite" systems, it is
more sensible to block it.
Could you ask a question at configuration time, probably defaulting to
not allowing relaying. If you want to be really clever, you could make a
guess based on earlier answers.
At the very least, a comment in the exim.conf file would be useful.
I don't think the above would be very difficult to implement, but I may
have missed something.

Agreed, it is better if things work out of the box.
