Right - which makes "let" a "second class identifier" (sorry,
made-up-term), since it can't be used in "let[x] = y". I
shed dodecahedron-shaped tears at the thought.

In the end, I don't see any reason to write new code that is not structured
as a collection of out-of-line modules (module files). Who knows, I might
be missing a valid use case for non-module scripts though...

Yes, but inline modules (actually pre-loaded module registrations) within a
larger out-of-line module:
// implicit strict because we're in an out-of-line module here
module "a.js" { ... }
module "b.js" { ... }
export * from "b.js";

I think this is a valid point, actually.

Nah - all dry humor there. I have 4 small children so this is about as
much fun as I'm allowed to have on a New Year's Eve.
The "compromise" is actually serious, though. To reuse the feces metaphor,
it doesn't so much polish the turd, as set it right out on the sloppy-mode
sidewalk. Won't be long before people start riding their ES6 bikes on the
strict side of the street.
Happy New Year!
