In order to make it easier to add new permissions the language specific files for permissions should be removed in favor of a general file for all languages. (similar to the sysprefs.sql file) Descriptions could be hardcoded into the template and be translatable via po files.
We still have a sql file for each language that needs translation. Not sure, we want to change that but updating version to master.
Resolved long ago - it's all managed in a template file now and one global .sql file.
