What would a 1JS-friendly strict mode look like?

Strict mode is a static, compile-time setting, not something that can be
modified at runtime. Hence, your suggestion falls short, because it would
be a runtime setting.

the reason why a "floating string" was used is to not introduce syntax that
older engines would trip over. Something like `use strict` (without the
quotes) would cause that. You might say that `scope.set` would only be
allowed at compile time or something, but that would be problematic both
because it's not backwards-compatible (what if code uses a collection
called "scope"?) and because it's not distinguishable from normal code.

Also, "use strict" has been around for years and nothing will ever get it
removed/replaced, anymore.
