I suspect that this gets some complaining off our back, but I *also*

something like this and then blaming us and causing a huge pain down the 
line when we've supported this and people want "extended semantics" that 
are no longer clean.

But I'm not sure how valid an argument that really is. I do happen to 
believe in the "give them rope" philosophy. I think you can probably screw 
yourself royally with this, but hey, anybody who does that only has 
himself to blame ...

That's exactly my argument when I had an exchange with Nico on
this thread.  I haven't decided if I want to make them (I sent
out a replacement patch for the tip one, and added another one)
merged in 'next' yet for that exact reason.
