Are there any Web apps at Google or elsewhere currently using  
SharedWorker? Would any of them still use it if they could switch to  
SharedScript? Has any app team specifically requested support for  
*both* SharedWorker *and* SharedScript? (Serious questions, since the  
justification for SharedScript is largely based on Web developer  

Note: if SharedScript was really globally shared it could be used to  
implement shared workers - simply have the SharedScript manage the per- 
app Workers.
