...in the application. Not in PHP. There's a distinction there often lost in the commentary on
this bug tracker.

I'd like to point out that this actually is a security issue.
LOCAL INFILE can be used by a malicious server to exfiltrate files from the client. Disabling this
option thus can certainly have security implications.
This caused an issue in phpmyadmin where they thought they set that option, but it wasn't
active:

Active support for PHP 7.1 has ended more than a month ago[1],
i.e. this branch will only receive security related fixes. Since
this issue does not seem to be security related, please check
whether PHP 7.2 or higher are affected as well, and change the
âPHP Versionâ field accordingly.
