Yep, but only as an *optional* feature...

Well, that can get really hard. I'm not going to add this feature unless 
we can make it reasonably straightforward to implement...

Isn't it?

Some thoughts:

- the optimal number of optional features in a spec is zero (I've stolen 
this, I'm not sure who said it first)

- let's concentrate on resolve the open issues in the spec instead of 
continuously inventing new ones...

See above. Unless we can agree on something simple, I'll prefer not to 
it at all (for now, that is).
