@andypost , please explain how Mink method signatures are affecting/blocking Drupal?

Deprecation warnings affects tests so they fail.
In production you can disable this warnings

For example this pipeline

Testing Drupal\FunctionalJavascriptTests\Tests\JSWebAssertTest
    E                                                                   1 / 1
    (100%)
    Deprecated: Behat\Mink\Exception\ElementHtmlException::__construct():
    Implicitly marking parameter $exception as nullable is deprecated, the
    explicit nullable type must be used instead in

Good. Doesn't look like a BC break.

I did update of comment with example

I checked files with $ php -d error_reporting="E_ALL" -l Mink/*/*/* to make sure no more deprecations left
