John, please take a look at the RFC:
https://wiki.php.net/rfc/source_files_without_opening_tag
I am not proposing any backwards-incompatible changes that would
affect existing code. Code that isn't interested need not ever take
advantage of the feature and can interoperate with code that does. I
realize there is confusion about this because of a separate and
unrelated RFC to actually eliminate <?php.
I agree that the security argument is bogus, but it was never one of
my reasons for this proposal.
