Thanks Kevin ... just asking: do you propose this change because the syntax is wrong or because you prefer the syntax with thearguments word in it? I'm asking because not addingarguments is valid ... I've just checked some Symfony apps of mine and sometimes I don't addarguments in some service configuration. Maybe I'm missing something here?

arguments can be omitted when it's the only key to be defined.
Refsymfony/symfony#21313 and#7441.
I would close this one.

Thanks a lot Jules 🙏 That's the confirmation that we needed here. Let's close then. Thanks!
