Comment (by nextendweb):

 > Another note: Realized that some of these functions may be used for
 downgrades too, so passing true for force more might make sense.

 If I read PHP source code well, it checks if the modified timestamp is
 equal or not:
 Line 1069 ->{{{if (zend_get_file_handle_timestamp(file_handle, NULL) ==
 persistent_script->timestamp) {}}}

 https://github.com/php/php-
 src/blob/e9f295ac849aa72304eb6ca01c6289a928cc77dc/ext/opcache/ZendAccelerator.c

 So If you downgrade, the modification time of the file will change, so
 force is not required.

 Maybe a PHP developer should confirm it.
