While I can't speak of 'all jurisdictions', just as a matter of common
practice in open source projects this is not so, and I'm not sure what
the notice 'ensures'. There is no particular *need* to have a
copyright notice and license grant in each file; if that were so then
probably half or more of all open source projects, including, no
doubt, OpenStack dependencies, would fail the test. There are some
arguments in favor of having such notices in each file, but there are
also arguments against (well, particularly with respect to copyright
notices, as over time they tend to become misleading as indications of
the actual provenance of the file in question).

Aaron Williamson wrote a good article on this topic, though I don't
agree with all of his recommendations:
