Hi, you are right, we changed the wordcount plugin to be an opt-in as in v11 (for proper v11 backwards compatibility)

That means wordcount needs to be loaded either via the legacy config:

editor:
  config:
    extraPlugins:
      - wordcount

Or via the newer importModules syntax:

editor:
  config:
    importModules:
      - { module: '@ckeditor/ckeditor5-word-count', exports: ['WordCount'] }

I guess it's likely that most people "copy" their existing v11 configurations also into (new) v12 configurations, so it's likely that those, who intended for wordcount to be enabled, have extraPlugins[] = wordcount defined.

Hope it's fine to close this ticket for that reason?

Yes, it's fine for me now. Thanks for the clarification. I'm closing the ticket.
