My bad. I was under the (false) assumption that PHP 7.2.0 generates an E_ERROR
(and that an E_ERROR would continue executing the program) due to the diff
http://git.php.net/?p=php-src.git;a=commitdiff;h=c05cbd1e775fa69ed9939796a908390f2bfb4459
but 7.2.0RC6 generates an E_WARNING.
So forget what I said about E_ERROR.
The real question remains: Is it considered a recommendation or a requirement?
The libsodium documentation says it is a requirement but the PECL/PHP7.2.0
treated it as a recommendation.
If we want to value BC then it should be kept a recommendation (i.e. E_WARNING)
for future release but if we switch to the (libsodium-suggested) interpretation
of treating it as a requirement then I agree that it'd be better to do this in
7.2.0 when libsodium is introduced into PHP core.
So you convinced me that we should convert it but in that case I'd do it for
7.2.0 even though we are in the final RC.
