Can you please confirm that this provides any practical benefit?
I feel like the Lua scripts are small enough and that this might provide nothing in practice.

Every time the lock is aquired OR tried to be acquired, the script is sent.

Here is a reproducer:

<?php

include(__dir__.'/vendor/autoload.php');

$redis = new \Redis();
$redis->connect('127.0.0.1');
$store = new \Symfony\Component\Lock\Store\RedisStore($redis);
$factory = new \Symfony\Component\Lock\LockFactory($store);

$lock = $factory->createLock('test');

echo 'Init'.PHP_EOL;
$lock->acquire(true);
echo 'Acquire'.PHP_EOL;
sleep(5);
$lock->release(true);
echo 'Release'.PHP_EOL;

I launched this script twice to get concurent access and retries in blocking part. See Network part of https://blackfire.io/profiles/compare/1c91192d-a1c4-4451-837c-839a1df61e54/graph

Thanks for the Blackfire comparison!
I'm not really convinced this is worth the added complexity personally...
