Because when we change the default (not sure what that could be, 2030
maybe?), it will change the way existing files are treated except those
that have a `lexical-binding:` cookie.  Clearly, this is dangerous and
so we want to minimize the number of those files until then.

That's the motivation also for the proposal to add a warning when the
cookie is absent.
