That seems reasonable to me.

I would guess that 3 or 4 significant, but not very novel ones is  
about the upper limit, based on experience from DAWG. The situation  
here is a bit different, it feels more like uncharted territory as  
many of the suggested features don't have a sufficient number of  
implementations. On the other hand we have to fit in with existing  
SPARQL syntax and semantics, which should make things quicker.

To complicate it further, some features work as natural and simple  
extensions to other ones, eg. if we choose to tackle subqueries for  
example, then negation (UNSAID etc.) is an obvious and straightforward  
addition, but taken in isolation, it's probably a pretty big task to  
specify either.

I would prefer to rank them, but I anticipate it being difficult to  
interpret the results meaningfully, unless there's more consensus that  
we saw in the straw polls.
