Denys I prefer to not add extensions like these "just in case", as they often gets abandoned or disappear completely (this vendor already had some extensions removed and he even have 2 fresh extensions for telegram auth, so it looks like he is experimenting with this). Currently there are ~100 extensions registered on Packagist but not available on Weblate - most of them are some kind of personal forks or niche projects and IMO it is just wast of time to translate these. I could add them if some actual users ask for it or dev announce it on discuss (that should indicate that is real extension and not an experiment that wil be removed next week), but adding all extensions from Packagist to Weblate is just not worth the effort.
