Discussed with Niklas. We see no use cases we want to maintain in updating translations from a file that was first uploaded to the wiki, or a file that is uploaded from a URL. Only leave importing a file from the user's local computer on Special:ImportTranslations. This also reduces choice on the page, and leaves one single workflow.
