I'm really hoping it does end up working well and that we can train many
people to do it.

I actually like the wording of "some reasonable reason".  I'll see if I
can work that in rather than exceptional or unusual.  I agree with the
change in emphasis you're trying to make, but at least on this side of
the pond, I'm not actually sure unusual connotes more common than
exceptional.  I suspect the real place where this matters is how it gets
written up in policy.

The Haskell exception for example will not be rare at all in that part
of the archive.
