@ArthurZaharov, I think since this template can be used both in a public project and in a private one, it would be possible to write two files (one parallel, other sequential), for example. But I think that since projects are usually developed in private repositories and not everyone uses paid Github Actions, it makes sense to leave everything as it is now.
