I want this particular extension to import those files that have suppressed revisions/versions, so that it can absolutely replace CommonsHelper.
Topic on Help talk:Extension:FileImporter
Thanks for your feedback. In the past, the development team investigated the question whether files with suppressed revisions can be imported, but found out that this is very hard to do. You can find more information in this ticket: T225588
Best,
Johanna
Has it been finished? This question is the reason why I reopened this topic.
@Johanna Strodt (WMDE): Also, I hope that the development team finds a solution to this problem.
T225588 mentioned above concerns revisions that are not hidden in source wiki. I'm not sure to what degree that's relevant here.
T162255 and T173836 also explored hidden revisions/file versions. It seems these tickets necessarily don't advice against importing such files, though the decision initially was to output an error message.
