Yes, I did this on purpose because this is mostly an internal detail. In the current docs we don't even mention anything about the third-party parser used nowadays.

I thought about closing this as "won't fix" ... but since we're changing the default parser, a brief mention about it could be needed.


Starting in Symfony 7.4, applications running on PHP 8.4 or higher will use
the native HTML5 parser provided by PHP. All other applications will continue
to use the third-party ``masterminds/html5`` parser, which is installed
automatically when installing the HTML Sanitizer package.

Basic Usage
