Only if the new keyword is used in the script or anything it
imports. This is exactly like using new syntax (u'...') or new
library features (unicode('abc', 'iso-8859-1')).
I can't think of anything that gets included "by convention" that
breaks anything. I don't recall a proposal that we should casually
add pragmas to our scripts if there's no need to do so. Adding
pragmas to library modules is *not* part of the issue; they'd only be
there if the version of Python they're part of supports the syntax.
