Since I haven’t received any comment yet, I just wish to point here several minor issues reported on Phabricator:
- to use interwiki prefixes instead of external link syntax in system message (but maybe it is not possible?)
- if FileImporter is supposed to work on MetaWiki (but maybe it should only works on Commons?) an interwiki prefix should be fixed
- in one place, NowCommons template name seems to be not internationalized
- an inconsistency may occur between doc and real messages if two different translators localize messages at issue.
