You're being downmodded for not providing any supporting arguments, but there's some compelling protection for malicious modules in these other JS implementations.
That's... weird. And kind of hypocritical, given the quality of your own comment which (a) mentioned downvotes and (b) used a few more words that boil down to "module protection". At this point I'm not exactly elevating the conversation either, for which I apologize. But I do think brief comments like mine and the one I replied to are perfectly fine.
