It's a good point (and I'm not one to "encourage strict mode" if there's 
no payoff for developers, but before agreeing, can you enumerate the 
cases that matter inside an arrow function body?

Without arguments runtime semantic shifts, and with |this| lexical, 
there aren't many strict mode changes left IIRC, and they are pretty 
edgy edge cases.
