Can we add a require-dev section for drush/drush?

Sure, Sharing a new patch. Please review

This is looking really nice. Just a few small nits.

   should this include an OR and include drush 10, 11 and 12 as well? Or is the version not needed at all? Actually, test things but I don't think the entry is needed at all. See my later point about changing class namespace.

   Can we add an assert about the messages to include, "Truncate realname table."?

   $this->assertStringContainsString('Truncate realname table.', $this->getOutput());

   If the namespace changes to Drupal\realname\Drush and implements a static create() method, then I don't think any of this is needed. It will get auto bootstrapped and discovered.

   public static function create(ContainerInterface $container): self {
       return new static(
         $container->get('database')
       );
     }
   

Thanks for the review. Sharing new patch covered point 2.
Regarding points 1 and 3.

It seems it will be required for Drush 10.

Based on the provided documentation https://git.uwaterloo.ca/libraries/drush/-/blob/11.x/docs/commands.md, it appears that including the drush.services.yml file and the /src/Drupal/Commands directory is indeed required

Not sure about dependency injection based on the following document it has two way to use dependency injection
https://git.uwaterloo.ca/libraries/drush/-/blob/11.x/docs/dependency-inj...

Please correct me if my understanding is not clear.

https://git.drupalcode.org/project/migrate_tools/-/blob/6.0.x/src/Drush/... has passing green tests w/ drush 11 and drush 12. I had to limit support to at least drush 11 as I couldn't get drush 10 and 12 to both support things at the same time. But since drush 10 no longer is supported, I think that is OK.
