Since Symfony 6.1, relying on the static property "$defaultName" for setting a command name is deprecated (https://github.com/symfony/symfony/commit/ca3458c8781eafd9ff40bac50a254334e526dc10) The replacement way is to add [Symfony\Component\Console\Attribute\AsCommand](https://github.com/symfony/console/blob/c3ebc83d031b71c39da318ca8b7a07ecc67507ed/Attribute/AsCommand.php) but php attributes are available for php8.0+ and this library supports php7.2+. I could provide a PR for this change but that would remove support on php7.2+. Is it wanted ? Maybe it's time to release a 1.x version ?
