To be honest, that suggestion confirms one of my fears about "1JS" -- ending up with a more complicated language with ad-hoc rules about which mode applies in which context. Please let's try to resist the temptation. As much as I would like to encourage strict mode, I think we should keep it orthogonal to other constructs as much as possible. I can bear tying it to modules, but let's not go any further.
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.
