The advisory says of the INI-diagnostic consumer under FPM: "FPM is conditionally exposed when nginx, Apache `mod_proxy_fcgi` or another frontend sends `PHP_VALUE`/`PHP_ADMIN_VALUE` parameters that produce a diagnostic before request initialization. FPM pool values are applied when a worker starts, and `.user.ini` is applied after normal initialization. They do not provide the same early consumer."
