It seems that 'Drush Patch File' (https://bitbucket.org/davereid/drush-patchfile/src/master/) isn't compatible with Drush 9. It, however, has one important function - Patch Status - which enables developers to check that all the required patches were successfully applied.
I was unable to find any way how to do this via the actually recommended Composer patch management (cweagans/composer-patches)... Is there any way how to (via Composer or Drush command) check the status of the patches? Or is there a clone of 'Drush Patch File' working with Drush 9?
Any help highly appreciated!
