False positive "unused dependency `ext-mbstring` " when run on PHP 8.3 and `symfony/polyfill-php84` is used

[LastDragon-ru]

Configs

{
  "require": {
    "ext-mbstring": "*",
    "symfony/polyfill-php84": "^1.31"
  },
  "require-dev": {
    "shipmonk/composer-dependency-analyser": "^1.8.4"
  },
  "autoload": {
    "classmap": [
      "src/MyClass.php"
    ]
  }
}

<?php declare(strict_types = 1);

class MyClass {
    public function trim(string $string): string {
        return mb_trim($string);
    }
}

Actual

PHP 8.4

Found 1 unused dependency!
(those are listed in composer.json, but no usage was found in scanned paths)

  • symfony/polyfill-php84

PHP 8.3

Found 1 unused dependency!
(those are listed in composer.json, but no usage was found in scanned paths)

  • ext-mbstring

Expected

On PHP 8.3 it should not report that ext-mbstring is unused because mb_trim is related to ext-mbstring.

Proposal

Maybe some way to tell composer-dependency-analyser about extensions and their functions, but it should be "soft" (= should not lead to report about unused symfony/polyfill-php84 on PHP 8.3).
