I kind of agree with your original comment about removing the kludge,
since the kludge does go against the spec ...

... a couple of thoughts to that effect:

1. this won't be 'in effect' until v7.1 comes out anyway
2. v7.0.2 will still have the kludge and will be available if ppl *really*
need it, no?

My vote is to go with Tom on this and remove the kludge ...
