Because the document has now such a direct and ambitious title that
~most of the target audience won't even read the text beyond the
title, hence this message won't be delivered.

This is exactly the trick (but with exactly the opposite sign) PCI SSC
performed three years ago when they published the document called
"Migrating from SSL and Early TLS, version 1.1" and the general public
widely believed that the document deprecated TLS 1.1 while what it
literally meant under "Early TLS" was ultimately TLS 1.0. Only the
*document version* was 1.1, but it was enough for quite a lot of
people who sometimes didn't even read the document at all but rather
sticked to short summaries by Arstechnica, The Register and the likes
(who, in turn, quite frequently don't read documents carefully

Might play well though if the title is changed.
