How do I generate-content of a particular type with drush 9.x+ root@0a581055a6ad:/opt/drupal# drush genc 10 --types=article


  The &quot;--types&quot; option does not exist.

Drush Commandline Tool 10.3.4

According to the documentation this was an option with drush 8.x, but I don't see any equivalent in drush 9.x and up. What is the intended way to invoke genc for a particular node type with this new version of drush?
Yeah, it's --bundles now. That's also what the error output is telling you already when echoing all possible options.
