I have the same problem.
Im my fork (diff is here) I added support for Symfony7, but my changes are not backward-compatible.
The base class for command requires ContainerInterface from Symfony namespace, but ServiceLocator implements ContainerInterface from Psr namespace.
Thats why I have not yet create PR. I am looking for solution.
Also I need to test other commands.
