I think I gave up too easily before, I'm going to have another stab at
this because you're right - it is more logical. It's early enough in
the life of this feature to change the ground rules about it's
origin...

I'm not promising anything more successful, but it makes sense to aim
for this - if only for the consistency aspect.
