The module creates a general.pot file in a sub directory called custom in the local translations directory. This file is imported after the other translations by a call to the command drush locale:import and passing in the filename.
It's good that the custom file is imported after other translations because it gives you the opportunity to add strings from core and contrib to a custom module and then use this to override the translations (and have it maintained in git and alongside other translations) but it does mean that this file would not be imported if you ran drush locale:update or you used the UI.
Can we use hook_locale_translation_projects_alter() to make locale aware of the general file.

This works great. Might open an issue to try to fix the drush deploy hook clashing issue.
