As far as I know the only reason it's there and hasn't been removed is 
because it's used to implement debugger watchpoints [1].  And the only 
reason it's web-exposed is because SpiderMonkey has not prioritized 
being able to expose APIs to privileged code but not the web (something 
that think should get fixed).
