We're going to remove this argument in Symfony 8 anyway.

-Using a HTML5 Parser
-~~~~~~~~~~~~~~~~~~~~
-
-If you need the :class:`Symfony\\Component\\DomCrawler\\Crawler` to use an HTML5
-parser, set its ``useHtml5Parser`` constructor argument to ``true``::
-
-    use Symfony\Component\DomCrawler\Crawler;
-
-    $crawler = new Crawler(null, $uri, useHtml5Parser: true);
-
-By doing so, the crawler will use the HTML5 parser provided by the `masterminds/html5`_
-library to parse the documents.
-
-.. versionadded:: 6.3
-
-    The ``useHtml5Parser`` argument was introduced in Symfony 6.3.
