It should be noted that we did not want to rock the boat too much with 
our proposal, so we stuck with the existing names.  I think the current 
spec as written has the same issues.

I agree with this.  We should probably file a bug about this.

I agree that Request seems confusing and seems to be contrary to what 
other specs use.  We should try to follow what other specs do here.

This sounds good as well.

Making it easier for someone to look at the method names and just know 
how to use the API seems like a good goal in my book.
