No. This all comes down how the file is evaluated and that is determined whether the file is treated as Script [1] or Module [2]. Modules are always strict and Script is sloppy unless it starts with a use strict directive. Traditionally all source files have been treated as Script but in ES'15 we provide another hook for the embedder to invoke which allows the source file to be treated as a Module [3]. The idea is that the module loader spec [4] will use this hook.
