However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

It seems like you assume a concrete implementation of the interface `Kevintweber\HtmlTokenizer\Tokens\Token` to be always present. This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass.
