wordfence-waf.php (auto_prepend_file) change in WF 7.5.3

Am I correct that the note in the Changelog for WF 7.5.3:

Improvement: Switched to relative paths in WAF auto_prepend file to increase portability

Doesn’t impact a site that is updating from 7.5.2? That is, on update, WF doesn’t try to modify wordfence-waf.php, and the change only affects:

1. new installs
2. if “REMOVE EXTENDED PROTECTION” is clicked on the Firewall Options screen

I want to make sure before I update to 7.5.3 on several sites, because I have added

define( ‘WFWAF_STORAGE_ENGINE’, ‘mysqli’ );
define( ‘MYSQL_CLIENT_FLAGS’, MYSQLI_CLIENT_SSL );

to wordfence-waf.php and don’t want to lose those changes upon update to 7.5.3.
