Thank you. :-) But what I meant was: Right now we don’t require one approach
or the other for this specific instance. Do we want to choose one?
I think in this case it makes sense to do the easiest thing. If it’s easy to
make the current tool accept both styles, let’s just do that for now. If the
tool currently forces you to choose one of the two styles, let’s choose one.
