Per https://www.mediawiki.org/wiki/Requests_for_comment/UploadWizard:_scale_to_sister_projects : "Proposed change: What I would like to propose is to restructure the UploadWizard software to make the following functionality available to contributors: Edit text of each wizard screen on-wiki. Edit the flow of the wizard (which buttons exist on a screen, where they take) on-wiki. Context: This request is based on the following observations: English and Russian Wikipedia's article creation wizards appear to be entirely markup-based, with no JS. Contributors have the flexibilities mentioned above, but lack some nice flexible things JS would let them do, such as choosing a next wizard screen depending on multiple previous choices, or entering partial data to be carried forward from page to page. A product which has the flexibilities mentioned above would have the potential to be deployed across all sister projects. Another example use-case is the “Idea” submission at Meta which needs a wizard-like thing. Such a product would also have the potential to work a bit gadget-like, to address use-cases I call “interactive templates”, to aid in daily editing routine and make it more intuitive. A JS-based product of this kind is under development on English Wikinews. Multimedia Team mention they would start working “in the coming weeks”, making feedback pertinent earlier better than later. Editing on-wiki is more collaborative than querying editing files (like ones in an Extension) would be. Markup should also be less-prone to security risks."
It might actually make sense to break this up into several bugs. Gryllida maybe you'd like to file those and mark them as blocking this bug?
Making UploadWizard useful for all Wikimedia projects is certainly something the Multimedia team intends to examine. Whether that involves wikitext-based configuration (ugh :) or a JS toolkit which can be assembled from a gadget or something else entirely, it is too early to say.
