Yep, this would work too, at the expense of passing around information  
that frequently won't be needed, and not scaling particularly well as  
we add more projections.

That said, I think it would be simpler (and more RESTful: http://www.peej.co.uk/articles/hypermedia-as-the-engine-of-application-state.html) 
  for now on the client and server side to do what you suggest and  
reconsider in the future if a) we add lots more projections or b) we  
find the extra information in the protocol unacceptable.

I don't think it would be a terrible compromise to leave the work of  
adding projections to urls entirely to the client, but I'm all for  
keeping url construction simple (that is, entirely server side) for now.

I'll comment on and expand bug 11613 to include this work, thanks!
