That interface looks indeed useless since 7.1. @xabbuh can you have a look as you were the one making NameConverterInterface methods' signatures the same as the AdvancedNameConverterInterface in 7.1?
If this is what we want, we probably need to add @param phpdoc annotations to each method of NameConverterInterface for the new params, to leverage DebugClassLoader's deprecation system.

👍 looks good to me

@chalasr, the @param annotations are already on top of NameConverterInterface related methods.

Can you please rebase now that #58368 is merged to ensure tests keep passing despite an implementation exists in core?

Thank you @mtarld.
