excluding features from sloppy mode

Put everything new in ES6 as implicit opt-in for strict mode? It certainly
is the simplest of all options, both for implementors and users. It also
removes the "big enough carrot" problem. Any individual feature may not be
enough of a carrot to sway a user, and taken as one by one choice, might
leave room for devs to pick and choose around strict mode (if there ends up
being some perceived difficulty or annoyance factor). But I can't imagine
anyone opting out of everything ES6 provides just to avoid strict mode. The
only reason people are likely to avoid everything in ES6 is compat concerns
which is orthaganol to strict mode.

Or something like require all ES6 features be inside modules, which
accomplishes the same thing. I know I saw this discussion before, or
something like it, but wasn't able to locate it.
