Surely those words do not need defining.  :-)

Do you actually mean to ask how exactly I tested this?  The answer to
that is that I have used emacs with the change for a couple of hours in
my normal usage and found no issues.

This will not force any other files to use lexical-binding.  I don't
understand what makes you think it would?  AFAIK, there is only one
thing that enables `lexical-binding' and that is if that buffer local
variable is set to t.  (You can also provide the optional LEXICAL
argument to `eval', but I don't think that applies here.)
